Four the dearly departed
Yesterday, I casually suggested that the Cardinals adopt a four man rotation for the 2007 season. It would make acquiring a fifth starter unnecessary, and the roster spot that the fifth starter would take up could just be filled by one of the 20,000 relievers currently under contract. The reaction to the idea seemed to be skeptical, to say the least. I, however, would really like to see the question seriously answered. The benefits of this plan would be as follows:
- It gives more innings to Carpenter, Reyes and Wainwright, who are more likely to be good than the Bruce Chen-level player that the Cardinals are likely to sign out of the free agent pool if a stud starter doesn't become availible. Having our best starters throw more innings has an obvious benefit that I won't detail here
- It keeps Braden Looper in the bullpen
- As has been stated previously by both lboros and me (most notably in the context of the 2005 offseason, and the Suppan&Marquis for Vasquez&Quentin trade), for a team trying to win the world series, there is no bigger waste than money spent on a fifth starter--the guy won't pitch in the postseason, will command more salary than many of the guys who will be on the playoff roster. Doesn't it make more sense to spend tha tmarginal cash on a guy who will actually advance your team in the playoffs?
- As has been shown by this series of Baseball Prospectus articles, the four-man rotation doesn't really induce injuries, or, at least, the five-man rotation doesn't prevent injuries. Why are we having a five man rotation if we aren't trying to prevent injuries? After all, pitchers pitched in a four man rotation for the first hundred and ten years that major league baseball existed. Aside from possibbly the change of mound height, what has changed so drastically that pitchers can no longer throw on four days rest? After all, pitchers throw on the side anyway. Here, we'd be eliminating the side session, replacing it with another day of total rest and another start.
I'm not advocating that starter usage progress in the same way that it has in the past--I would limit all of our starters to a very, very strict pitch cap of one hundred pitches, perhaps less for Reyes and Wainwright. Unless the guy is in the ninth inning, and going for a complete game or a no-hitter or something, if he hits a hundred pitches, he is finished. No questions asked. Not throwing with the broken mechanics of a tired pitcher would remove almost all of the 'extra' strain induced by throwing in a four man rotation, right off of the bat.
Really, the only argument that I can see actually working against the four man is, as documented in an old comment here that I can no longer find, Carpenter seemed to have progressively better splits as he had more and more rest last year--turning from a shaky (by his standards only) starter on three days rest to 1968 Bob Gibson on five days rest. If that trend is not just a small sample size fluke, this whole idea might be somewhat counterproductive--you'd be increasing the number of innings thrown by your starters, but the one whose innings would be the most high-impact, for whom you are doing this in the first place, will pitch less effectively after the retooling. In this case, it would not make a ton of sense to give these innings to him.
Anyway, I'm not a baseball trainer, and I can't identify the true trend here, and really say definitively whether or not this would be a good idea. I can, however, say that in pure Moneyball terms, it makes a lot more sense to give this idea a try if it doesn't cause Carpenter's performance to decline. If nothing else, it would sure make a ton of sense skipping the fifth guy's start when an off day would allow for it.
Anyway, that's just my ideal winter idea for the day.

Good stuff Val
One thing, however, that I've never really appreciated about TLR is his use of the running game. I think he tries a little too often to send guys who aren't really good basestealers. Those stats are somewhat inflated by botched hit-and-runs, but still...that's not such great idea most of the time either.
There was a pretty good analysis of the Cardinal baserunning at Fungoes. For those of you who join me in Juan-dislike...here's even more reason: Juan is our worst baserunner.
http://stl.sabr.org/fungoes/?p=739
And, here's a little discussion about it at BTF:
I'd love to see someone try a 4 man rotation
That being said, I'd rather the Card didn't try it in '07 due to the 2 kids logging their first full year in the rotation. But what I do know? Heh.
Fifth man
If you're spending extra money on him -- paying him a premium because he's a starter rather than a reliever -- then you have to think he's better than some other guys in the pen. That wasn't the case with Marquis, but then again he never should've stayed in the rotation for the entire regular season.
If nothing else, that fifth starter should be an ideal long reliever in the playoffs, if your starter has an early appointment with the showers.
As for the pitch count, I agree with you, but I'd like to see that kind of pitch-count discipline within the current system.
We're paying good money to relievers anyway; we should never be afraid to use them once the starter gets past 100 pitches.
It's still not the best use of money

avg 7.83 3.9 2.1 0.5 6.9 0.60 0.780 6-1
And here's the full discussion. Pretty compelling stuff, in my view.
WOW.
I know Carp had another great year overall, but that's EIGHT full starts in which he DOMINATED. Some may say 8 starts is too small a sample size, but 1/4 of an entire year's starts (and 62.2 innings pitched) is hardly a microstat.
I'd say we should rule out throwing Carp on 3 days rest based upon that analysis alone.
Another important factor to consider is that Reyes was much less effective at the end of the year (2006), and according to some reports in Sept '06, he was beginning to suffer from "dead arm" syndrome. As a result, I would think he also would benefit from MORE rest between starts in order to stay effective, not LESS.
In fact, on 13 Sep 2006 the Cards skipped his scheduled start after Reyes had recently announced that he "was tired". His previous start was on 08 Sep in Arizona on the normal 4 days rest, and he had performed terribly, giving up 7 ER in 2.1 innings. With the skipped start on 13 Sep, he got 10 days rest before his next start vs MIL on 18 Sep...and he did well, 2 ER in 5.1 innings with 100 pitches. He then got 9 days rest and did very well again against SD, giving up only 1 ER in 6 innings with 108 pitches. I am still absolutely AMAZED that the LaRuncan brain trust couldn't identify this trend and then still decided to start Reyes on SHORT rest in that ugly attempt to have him clinch the playoffs on the last regular game of the season! The results of that start (5 hits, 2 homers, 4 earned runs in 2/3 inning) speak for themselves.
I'm certainly not opposed to the 4 man rotation in theory, but with what we know about Carp and Reyes I think going with a 4 man rotation would be a huge mistake for the Cardinals.
My biggest problems with this idea:
- We're relying on two kids, one of which has not started in the big leagues to my knowledge(or at least been a regular starter), and the other which TLR is STILL not showing full confidence in. Maybe there's no additional injury risk in this situation, but do you want to make the two guys that are the future of the Cardinals pitching staff the experiment?
- We basically already HAVE our fifth starter in Kip Wells. I know we can't go back and take a do-over, but if we were going to go into a situation of looking at a four-man rotation, then we needed to get a guy like Schmidt or at least someone along the lines of Lilly.
- What if an injury happens? Then our lack of depth in the starting rotation could REALLY hurt us. And if we haven't even made an attempt to stretch out Thompson to start or don't have a fifth starter, we're looking at a three-man rotation with the fourth spot being bullpen starts for what would likely be an already heavily used bullpen(assuming you'd keep the starters at a more conservative pitch count since they're pitching more often).
I don't remember how it worked out, but I may try to look up some information about that. If anyone else finds that, it'd be a GREAT thing to post.
the 2004 rockies flirted with the four man
Their top two guys in starts
Maybe this is four-man rotation based, maybe not.
That seems to be the problem with this discussion is that there's no reasonable sample size to work with since Baltimore in the 70s. Everyone that tries it seems to either have an injury or bad pitchers and they give up before they get anywhere with it. Could be because of the four-man rotation, but it could just as easily be a sign that a team with good starters don't need to resort to this.
It's a chicken or the egg kind of debate really.
To reply to myself....
A four-man rotation had relative success in 2003 with Toronto, although Halladay had two injury-plagued seasons after that. Appier, by most accounts, destroyed his arm with KC in 95, whether that was because of the four-man rotation or not, but the Weaver teams had pitchers who actually got BETTER in a four-man rotation.
I have a more thorough look at my personal sports blog: http://midwestsportsfan.blogspot.com
Take a read, give me more hits ;)
If anyone knows of any other four-man rotation attempts of any real length, please let me know, and I might append my post on my blog if I have time in the next few days before Christmas.
I like the four man rotation
I would not be worried about AW and AR in a four man rotation. Let's see what these kids can really do. This would really test if they are the future or not.
As far as the playoffs you only need four guys. In a short series and given the scheduled days off you want to only pitch your top 3 to 4 guys depending the series. You want your best, not your fifth best.
Of course if the rotation isn't working, they could always trade for someone and add a fifth.

they are NOT young arms
But, both will be 25 this year. I don't think that's what BP or anyone else considers young when preaching to baby a young arm along.

re: Appier
The Royals went with a four-man rotation in 1995 with Appier, Gubicza, Gordon, and a cast of fill-ins that included Tom Browning and Hipolito Pichardo (one of my favorite baseball names of all-time). Appier had a great first half of the season but the work caught up to him and he fell off a cliff at the end of June. He wasn't ruined by that, though; he rebounded to pitch well for terrible Royals teams in 1996-1997.
What really ruined him was a freak injury during the 1997 offseason in which he fell and tore his labrum while carrying presents up the stairs at his sister's baby shower during an ice storm. He was never the same pitcher after the injury. Seeing how Ape was unable to return to form after his labrum injury is why I'm skeptical about Mulder's chances of doing so. Ape sure was a hell of a pitcher before the injury, though.

Four versus Five man rotations
Also as I mentioned yesterday, while pitchers (or more to the point, pitches) have been more or less the same since the mid 1890s, hitters are bigger, faster and stronger now. This requires working hitters more carefully more often.

It was about the same time
If you re-raised the mound, built stadia with fences as far back as they were in the sixties, and abolished the DH, I betchya that you would see the 'decline' in pitchers' performance vanish.

by BigJawnMize on Dec 20, 2006 12:21 PM EST up reply actions
I disagree
Now, kids are put in a rotation even in little league because parents are afraid that the kid will blow his arm out before ever hitting high school. The arm is taught to pitch and rest.
My fear of a 4 man rotation is that if our pitchers don't have arms that are trained to handle that work load, they will develop problems not just for this year but for subsequent years to come. It would be really awful to kill Carp for the next 4 years rather than just accept that we don't have the team to win again this year. Get a 5th starter, throw it up there and be happy that for the entire 2007 season, we are world champions.
(Plus, I think in a year or two, as team are over extended on contracts from this year, we can scoop in and pick up some really quality players for relatively cheap.)

Uh, what?
Kids who end up in the majors have probably played 5 or 10 times as much baseball as they used to. yeah, I'm just making up a number but it's a huge difference.
American Legion teams. Traveling teams starting in junior high, maybe earlier. Organized baseball starting with t-ball at age 4.
I agree with Westy
Sorry, I din't mean to belabor a point
While pitches are bigger and stroger and condition themselves better, physiologically what limits pitches has been the same since the mid 1890s. This is why the fastest pitchers regardless of size and era (e.g. Amos Russie to Randy Johnson) top out at the mid to high nineties and the overall best (e.g. Christy Matthewson to Roger Clemmens) consistantly are in the high 80s to low 90s with pinpoint control.
On the otherhand batters are bigger, stronger and swing faster and harder than they did before. I agree that moving fences back, abolishing the DH , raising the mound and perhaps resizing the strike zone would improve pitchers performance, but I think there would be a differnce from say the 60's to today.

When did it start?
A theory is a guess with a better name.
The five man rotation started in the 70s
Remember baseball strategies and opionions have been historically slow to react to changes in the game. It took years for most teams to adapt hitting strategies to the live ball of the 20s and 30s. Third base was considered more importantly defensively than offensively well in to the 30s. Cobb was considered a better player than Ruth until 1950 or so...

Why 100 pitches?
by ilillillli on Dec 20, 2006 11:27 AM EST reply actions
I'm sure the real number isn't exactly 100
it seems to me....
Couple of things
- The five man rotation was started by the Dodgers because they had five good starters and not to save anyone from injury. As typical in baseball the other teams missed the point and went to a five man staff as well thinking it was the extra day of rest that helped, ignoring having good pitchers and a pitchers ballpark helps more.
- You can't use Carp's starts on short rest because it's not the same thing. Telling Carp he's starting today instead of tomorrow isn't the same thing and calling him this week and saying hey Carp we are going with a five man staff so you might want to change your workout routine over the next couple months.
- It's not the innings that hurt pitchers it's the number of pitches thrown when fatigued. The 100 pitch count is just a base, why? Because 100 is easier to remember (and really if they said it was 104 most people would just say you're making that up.) 6 ip per 40 starts or 240 innings would be easier on an arm than 7 ip per 32 starts or 224 innings. That's the idea.
This is hilarious....
The Cubs believe the Cardinals damaged Jason Marquis' psyche when they asked him to take a pounding in a couple of games--13 runs in five innings against the White Sox and 12 runs in five innings against Atlanta--that destroyed his ERA. He became the first pitcher since Chubby Dean of the 1940 Philadelphia Athletics to allow 12 earned runs or more in two starts in the same season.
Gotta love the Cubs
Hilarious, Indeed
As for the four man rotation, I'd rather go with a four-man and a tee (Sea Cow!) than four men and then over again. I'm sure the rest of the division would be tickled pink to routinely face our starters on three-days' rest.
And I'm sure

not to mention the pop flies
Maybe he should only be allowed to pitch in San Diego, LA, New York, and San Fran so that he can take advantage of pitchers' parks just to ensure his psyche survives the season. Oh yeah, 1 more pitchers' park he could pitch in -- Busch!
Not now, maybe later
However, the BP articles recognize that some individual cases may differ (particularly older pitchers), and DCGreg's statistics show that Chris Carpenter is much more effective with extra rest. So, file the four-man rotation as a good idea that doesn't fit well with our current personnel.
P.S. The anecdotal evidence in the BP articles that pitchers have sharper control on three days' rest doesn't seem to apply to Carp.
Four man won't work
We don't want to be the Cubs here . . . overworking out young pitchers until they're doomed to an eternity of injuries.

Blue Jays did it in 2003
http://espn.go.com/mlb/columns/neyer_rob/1562009.html
The Blue Jays toyed with a 4-man rotation in 2003, the pitchers??
Roy Halladay - 26 Years Old
Cory Lidle - 31 Years Old
Kelvim Escobar - 26 Years Old
Mark Hendrickson - 29 Years Old
Interestingly, Halladay and Escobar were both 26, same age as both Wainwright and Reyes....albeit
with considerably more starts at that point in their career than Wainer and Reyes.
Now, I can't determine how long the Jays stuck with it, here's a list of games started by Blue Jay pitchers in 2003:
Roy Halladay 36, Cory Lidle 31, Mark Hendrickson 30, Kelvim Escobar 26, Doug Davis 11, Tanyon Sturtze 8, Josh Towers 8, Pete Walker 7, Corey Thurman 3, John Wasdin 2
As of June 29, 2003 here are the starts by pitcher:
Roy Halladay 18, Cory Lidle 17, Mark Hendrickson 16, Doug Davis 10, Kelvim Escobar 9, Tanyon Sturtze 8, Pete Walker 4
So after June 29, 20 starts were made by someone other than Halladay, Escobar, Lidle or Hendrickson...so apparently they didn't stick with. Good article though!
The article also mentions the injury troubles for Kevin Appier in 1995 when the Royals went 3-man with him....

4 Man Rotation?
Agreed
by Bird Watcher on Dec 20, 2006 1:41 PM EST up reply actions
Pitching between starts...
Even Carpenter has said that he benefits greatly from his pitching in-between starts (finding mechanics that are off, etc), and you would think it would benefit young pitchers like Wainwright and Reyes even more. Think of it like a hitter without batting practice or a fielder without fielding practice. We wouldn't even think about this in football or basketball. (Unless it is Allen Iverson)
A 4 man staff may not make a pitcher more injury prone, it may just may make them worse.
I like the 4-man idea
Considering that the manager is La Russa and he doesn't push his starters as is, I would be OK with it. And it isn't like they would have no insurance against an injury.
I'd rather have Carp, Reyes, Wainwright and (a healthy) Wells taking the ball 35-36 times than seeing Braden Looper or someone else wasting starts.

We'll need one
That was just a lucky thing in 2005, the way the off-days worked out to let Morris rehab.
I think the best argument against the 4-man rotation plan was made by MRCARD above, that the starters need the side sessions to keep their mechanics right and to study the next lineup they'll face.
I'm not sure what the issue is here that has youse wanting to go with four starters. What's the problem with plugging in a cheap back-of-rotation starter like Jamey Wright, Chris Narveson, or Chris Gissell and keeping your horses on the schedule they've trained their whole professional careers for?

Tagg Bozied
What about
Pros:
- save on the salary of the #5 (or #2 as some have opined) SP that conventional wisdom says we still need
- bring Narveson and Thompson along slowly in their SP role, but makes a small commitment to the youth movement
- doesn't take up that #5 SP slot in the playoffs, since you only need 4 there, as someone mentioned in a previous post (maybe an earlier thread?)
- #5-SP-by-committee means fewer bullpen arms for the other 4 starts
- whoever the SP is doesn't get to build up any consistency
- an injury to one of the first 4 SPs leaves an even greater hole
The handwringing over who's available vs. the market rate vs. the Bruce Chen-type pitcher, etc., etc., made me think of considering this approach.
Can it work over the course of a full season? Maybe. Will TLR/Dunc try it? Probably not. It's idle speculation on my part. But what else can we do re: baseball on December 20th?
I've put on the flame-retardent suit; let 'er rip, folks.
TSF
The next step to your idea
Rotation Possibilities
- Four-man rotation: A strict quartet of starters, with the occassional spot starter thrown in for extra rest or a doubleheader.
- First-man rotation: A box-&-one setup, with your ace hurler pitching every fifth day as the schedule allows, the other starters shuffling.
- Fifth-man rotation: A swing starter works every fifth game after a scheduled off-day.
- Five-man rotation: A basic setup, with everyone taking their turn.
The four-man rotation would be very difficult to implement & maintain, as the pitchers coming up through the team systems are unused to the workload that it takes to make it truly effective. Not that the workload is any harder per se, but that it is different.
In essence, you would have your top four guys starting 38 game each, with 10 starts handed over to a long reliever out of your pen. As long as the manager doesn't replace that fifth starter with your 8th-best reliever (read: preferably bring in a PH/PR/defensive option for the bench), I think it's a good use of resources. That assumes you have the goods to actually pull it off.
The first-man rotation has been used plenty of times, most notably for the Cardinals the past two years as Carpenter has made his September run toward the Cy Young. For Chris, it appears that he responds better when he doesn't have the additional pressure thrown on him and he has the occassional extra day of rest. (His final month the last two years have been brutal compared to his earlier efforts. (Nevermind his shutdown in 2004.) But for many other big game pitchers (surrounded by lesser pitchers), this is the most effective use of their services.
The fifth-man rotation would have been, I think, the best situation for Reyes to have encountered last season, assuming everyone else had performed along historical precedents. Four solid starters receiving regular rest and work, plus the option of working in the young hurler in a controlled fashion and reduced pressure. Looking back, nearly every facet of that plan went to shit, but it doesn't mean that it's not a sound strategy.
(Another benefit to this rotation option is that, all other things being equal, the fifth starter is already accustomed to his reduced role and would be less likely to balk at a full-time move to the bullpen come playoff time.)
The basic problem with a strict five-man rotation is that it is a waste of resources. Having five solid starters gives you an advantage in that your fifth best guy is almost certain to be better than their fifth & you can steal a few more regular-season victories, but it is a waste come playoff time. Conversely, if you have a guy who wouldn't be a great loss if he was relegated to the bullpen, why the hell is he getting 32 starts a year?
Of course, this is the setup that nearly every team is used to. Heck, it's as simple as you can get and there are no conversions to make to your staff. But the point of a manager (both in baseball and for working stiffs) is to get the best use out of the people that he is given, not to keep it so simple he doesn't need to put any real effort in to his job. [Tangent/rant detected; conversation topic terminated. jk]
Given our current starting pitchers, their respective histories, and our fall-back options, I think it's best if we follow a first-man rotation, with maybe an occassional extra day of rest awarded to Carpenter. His production is too valuable to waste precious starts with scrap-heap reclamation projects.
It seems like
The problem as I see it is more psychological than anything else. Pitchers have been trained to pitch every 5th day so getting them accustomed to the preparation would be the most difficult thing. Their routine would be upset, at least in the short term, and figuring it out could cause some hardship for the staff. Plus, a couple of bad starts and then the pitchers think it's the 4 man and the routine and their confidence is shot!
In theory I think it works but I don't think it'll work in reality b/c of the disruption it would cause among pitchers -- fearful they'll get hurt, how to prepare, etc.

4-man rotation
by gashaus34 on Dec 20, 2006 10:13 PM EST reply actions
I doubt the Cards are the holdup
four man rotation
1. the object of a four-man rotation is to give your best pitchers more innings. Hypothetically, those pitchers would be your four starters and closer. Carpenter, check. Wainwright, sure. Reyes, sure. and...Wells?
Carpenter seems to pitch better with more rest, Reyes and Wainwright have yet to log 200 league average innings in the majors, and Wells has been lousy the last two years.
2. your coaches have to know when a pitcher is getting "tired." LaRussa and Duncan seemed to have learned from the young Alan Benes and Matt Morris injury years that the 100 pitch count is not such an arbitrary number. I trust them to watch the count and the body language of a pitcher, but Wainwright, Reyes, and Wells have never pitched a full season for either. It takes a while to learn a pitcher and not many pitchers will say "take me out coach" on their own.
In my opinion, the Cardinals are better off with the uncertainty. More innings given to any of the four pitchers seems a disservice. Carpenter is now a big ticket pitcher. Stick with what works to maintain the value of the contract. Wainwright and Reyes are coming into a high pressure situation. Why put additional pressure on them? And Kip Wells has proven nothing.
The fifth spot in the rotation (as it is now) allows you the benefit of experimentation. LaRussa would not allow Looper to flounder long. Brad Thompson? Narveson? unnamed veteran pick up? Surprising rookie? Will it hurt the team in the short term-? Will Kip Well-? Will Wainwright and Reyes handle the pressure of starting-? Jeff Weaver started the final game of the season...in the world series!
Certainty is not a luxury the Cardinals have right now. Why bank the season on a theory, when the pieces do not fit the criteria?

4 man rotation, great idea

Basically they looks at a large group of pitcher that had 3 or 4 days rest and looked at their performance and health. They didn't find any evidence that the extra rest was helpful. The data points to the pitchers having slightly better control and making fewer mistakes in the 4 man rotation. Given that wainwright is the only non-control pitcher likely to be in the rotation this should benefit the type of pitcher the cards have.
Here are two clips
"I was able to obtain start-by-start data for all pitchers back to 1978. In the past 24 years, no less than 160 pitchers have made at least 8 starts in a season on both three and four days' rest. By looking at how their performance on varying amounts of rest, we can determine whether being brought back one day earlier had any deleterious effects.
The combined numbers of those 160 starters:
Rest IP H ER BB K HR ERA H/9 BB/9 K/9 HR/9
