round and round she goes . . . . .
just in time for the latest news about the cards' april rotation: a statty look at something called "starting-pitcher leverage" over at the Hardball Times. what's SP leverage?
according to derrick goold's sunday post at Bird Land about the rotation, tony and dave are practicing a form of leveraging. "The rotation is set as much for who pitches against what team as who doesn't pitch against certain teams or in certain ballparks," goold notes; this remark from La Tony reinforces the point:
| carpenter | mets | astros | pirates | pirates | cubs | cubs |
| wells | mets | pirates | brewers | cubs | reds | brewers |
| looper | mets | pirates | pirates | cubs | cubs | brewers |
| wainwright | astros | brewers | giants | reds | cubs | astros |
| reyes | astros | brewers | giants | reds | brewers | astros |
THT's formula is a simple one: you simply take the average of a given pitcher's opponent teams' winning percentages, and divide that by the winning percentage of all opponents on the team's schedule. let's carpenter as an example, applying 2006 winning percentages just to keep it simple. his 6 opponents had 2006 winning percentages of .599, .506, .414, .414, .407, and .407 --- an average of .458. now divide that by the winning percentage of all st louis opponents --- the cards' first 30 opponents had an average 2006 winning percentage of just .468 --- and you get a quotient of .98. so carp's first six opponents are 2 percent less difficult than the average cardinal opponent during that stretch.
as measured by 2006 winning percentages.
but obviously, this isn't 2006; we just used those figures as an example. to make this slightly more meaningful, let's apply some reasonable projections of 2007 winning percentages and see which pitchers are being leveraged by that standard. i'll go ahead and use the w-l percentages posted in RLYW's Diamond Mind projection blowout last week; i trust those numbers as much as i trust any. here are RLYW's projections for the cards' first 30 opponents:
| opp | games | est wpct |
|---|---|---|
| mets | 3 | .525 |
| cubs | 6 | .519 |
| brewers | 6 | .500 |
| astros | 5 | .494 |
| giants | 2 | .488 |
| pirates | 5 | .457 |
| reds | 3 | .451 |
over the 30 games, that averages out to a .492 winning percentage. now let's look again at which pitchers are facing which teams, and apply the THT leverage formula:
| 1 | 2 | 3 | 4 | 5 | 6 | avg | lev | |
|---|---|---|---|---|---|---|---|---|
| carpenter | mets | astros | pirates | pirates | cubs | cubs | .495 | 101 |
| wells | mets | pirates | brewers | cubs | reds | brewers | .492 | 100 |
| looper | mets | pirates | pirates | cubs | cubs | brewers | .496 | 101 |
| wainwright | astros | brewers | giants | reds | cubs | astros | .491 | 100 |
| reyes | astros | brewers | giants | reds | brewers | astros | .487 | 99 |
well, wasn't that a worthwhile exercise. . . . . . i'm so glad i went to the trouble. lest the whole thing (and this whole post) be a complete waste of time, let's make a logical adjustment here. leverage can be measured by things other than raw winning percentage. in this case, while the mets have the best projected winning percentage on the st louis schedule, they are definitely not the team the cardinals want the most leverage against --- because they play outside the division. the top nl central rivals --- cubs, astros, and brewers --- are the teams st louis wants the most leverage against. (i'll grant that the cards and mets might end up vying for the wild card --- but the same could be said of all the in-division foes, so that's a wash.) to reflect the greater significance of the games vs the cubs astros and brewers, let's assign a premium --- wild-ass guessing, i'm going to make it .050 of winning percentage --- and recalculate. here's the table, one last time:
| 1 | 2 | 3 | 4 | 5 | 6 | avg | lev | |
|---|---|---|---|---|---|---|---|---|
| carpenter | mets | astros | pirates | pirates | cubs | cubs | .520 | 100 |
| wells | mets | pirates | brewers | cubs | reds | brewers | .517 | 99 |
| looper | mets | pirates | pirates | cubs | cubs | brewers | .521 | 100 |
| wainwright | astros | brewers | giants | reds | cubs | astros | .524 | 101 |
| reyes | astros | brewers | giants | reds | brewers | astros | .521 | 100 |
dammit . . . . . all that pencil-scratching for nuthin'. that's not to say that tony n dave aren't seeking to exert leverage; they're simply applying different levers from the one described here. e.g., "the astros can't hit a curveball, so let's start wainwright vs them twice," or "wells has a 3.06 career era vs the cubs," that sort of thing . . . . . i prob'y should have spent my time looking into those. have at it in the comments thread, if'n you're interested.
i guess the most significant thing about the way the rotation has been set up is this: chris carpenter will get an extra day's rest 5 times in his first 10 starts. as we discovered during the postseason last year, carpenter thrives on extra rest. his era on extra rest last year (in 7 starts, including world series game 3) was 0.82; his whip was 0.585. he was completely unhittable on 5+ days' rest.
the other great thing about the rotation: it only has to cycle through one more time before the real games begin. st louis plays the marlins today; gameday link here.

Leverage
Good point...
Both of them have only two starts against better than .500 teams.
Me thinks it probably a combination of both, with protecting Carp and getting him starts and days off being the number one priority and protecting the younger kids secondary to that.
If they are really shaky,
I say, throw the lads right into the fire and see what they have. This is the big leagues!

Actually no...
The psych factor on pitchers has been well documented and the thought is not to get their butts handed to them the first couple of weeks so not only are they working on mechanics they are working on their own psych issues.
So I guess pitching

Just had another thought
but...
i think that tony really wants to beat the cubs, both because they roughed us up a bit last year, especially early on, and because pinella is their manager. thus, he has carp going twice. you may be onto something with looper; i simply don't understand anything about looper.

A couple of other things to consider
You factored in additional leverage vs. the Cubs, Astros, and Brewers, but maybe he doesn't consider the Reds and/or the Pirates "leverage-worthy" at all. IOW, maybe he only considers having his best pitchers facing the best teams and, if we did a mathematical calculation, maybe the Reds and/or Pirates wouldn't be considered at all. Or maybe the Reds would but not the Pirates. Not saying that's the way it should be done, necessarily, but maybe that's the way LaRussa and Duncan look at it.
Hope you don't feel like your time went for naught -- it makes for great discussion and I think you're right -- there is more to it than we're seeing -- the curve ball factor or pitchers' individual stats vs. hitters or teams.
Hahaha!
Do you think Tony and Dave Duncan know about Chris Carpenter's koufaxian propensity on extra rest? Maybe they could pitch him 31 times this year instead of 35, and give him 8 of those extra days off or so.

Extra rest
(Of course, last year they felt (correctly) that they couldn't afford that luxury.)

5 Year Deal
This will help two-fold
- He will be more likely to be healthy for the length of the contract.
- He is OUTSTANDING on extra rest so you are probably going to get the same amount of marginal wins out of him with the extra rest that you would have got by keeping him "on schedule"

Who you're competing against
Probability of competing against them / probability of competing against everyone
The probability of competing against the Pirates at the end of the season may be something like .1, while that against the Cubs or Brewers more like .8. You could also take wild card into account in this.
The problem with this approach is that you'd have to come up with a reasonable proxy for probability of competing against a team. The projected difference in the standings may be a decent measure -- if we're projected to be one game different form the Cubs, then the number is really high, while if we're projected to be 20 games ahead of the Pirates, it'd be a lot lower. Using projected differences in standings may work, because they are relative, which is what you're really looking for here.
In-division this might be pretty simple to figure out, but I can't imagine how you'd take into account wild-card possibilities.
What does everybody think?

Getting Right
by Birds on the Bat on Mar 26, 2007 11:14 AM EDT up reply actions
Exactly
I think the key point is that every pitcher who starts for you can, at best, help your own team to one win. "Leverage" comes in when you take advantage of him to give a loss to competitors at the same time. At the end of the season, it's easy to see who your competitors are. At the beginning, it's all about who you expect to be competing against, which is much more speculative and hard to measure.
Starting Carpenter against the Cubs in late September gives you obvious benefits. The benefits are less obvious in April, and may even be irrelevant if the Cubs fall off the cliff like they did last year. However, I think it makes sense to take an ex ante approach and look at expectations.
by CardFaninVA on Mar 26, 2007 11:46 AM EDT up reply actions
fixed
Excellent
You should probably figure that into the ex ante calculation. Knowing the near certainty that the Cubs will fall off the cliff will cause the relevant probability of it mattering in the standings to fall almost to 0 (except in the exceedingly rare case when Kerry Wood and Mark Prior are both healthy, which is clearly not the case this year).

Leverage = Matchups
I am generally happy to hear tlr talk about using the whole group and getting extra days in view of a long season. Given how anemic the offense looks so far, propped up in average by some destined for Memphis, it looks like some good pitching performances are going to get wasted by an inability to score. No reason to press on four starters early if that's how it's going to be.
by Birds on the Bat on Mar 26, 2007 10:46 AM EDT reply actions
Has anyone mentioned
And after the first run through...
Carp, Wainwright, Reyes, Wells, Looper
Just as it should
Looper
With Looper facing the Mets right before an offday, the whole bullpen can go out and have a good time after BLooper throws 3 innings and they'll have an extra day to get their strength back.
Overall, I'd guess it has a lot more to do with pitcher vs. team/lineup matchups than specific "importance" of games. For example, Suppan nearly always ended up with a start in Milwaukee, where he absolutely crushed for his stay here.

Perhaps you can relate, Larry.
On the other hand, much of science is testing hypotheses, and the test has to be objective. It can't be set up to "prove" your conjecture. You have tested a hypothesis and published your results and future scientists will benefit from your labors.

I have tickets to the April 9th game
Wells (by team)

CHC 3-3 3.06 ERA

Maybe Tony is just 'going from the gut' here??

The trouble with leverage
The only chances for changing that are (1) rest days and (2) skips for minor-league replacements or bullpen starts.
So yeah, there are some opportunities to maximize the chance of getting a win using match-ups, but they come at the expense of a stable routine for the starters--something Duncan and LaRussa have been reluctant to mess with.
by Red in Chicago on Mar 26, 2007 12:28 PM EDT reply actions
i respectfully disagree with
when they have starters they trust, they don't like to tinker --- and they trust all 5 of this year's guys so far. but if anybody other than carpenter hits a rough stretch in the early going, i'd expect them to start tinkering --- and doing it to maximize leverage (however they define it).

Sorry 'bout that
The dates were wrong for all of today's games, fixed now over at my place.
Fair point, Lboros
It would be interesting to see whether short rest for one pitcher canceled out the improved performance of another in a created match-up. Of course "canceled" might be a variable too, since the match-up could be against a division rival and the short-rest could be against the Marlins or something.
wainwright
I cannot wait for Sunday.

can we hope to keep him from going to ATL
(I completely agree -- he'll be amazing very soon.)
Wainwright/Reyes Meltdown?
You hear this discussed in regards to conditioning with rookie starting pitchers. The Tigers' pitching dwindling performance toward the end of the season and Jared Weaver starting out on the DL this year. You know, the whole idea that these young guys come up having pitched less than 150 innings a year and then they have to their expected to throw 200?
Add Looper to the mix and we have three pitchers in our rotation who haven't pitched that many innings in a season before. Our "projection" pools don't seem to reflect this concern either. I guess Mulder is an insurance policy on this, but that's not much insurance.
That's why I mentioned the immediate
Still..
Well, what's the alternative?
Nope, this is the price we pay for developing our own starters, and we have to pay it sooner or later. So we trust a couple of AAA pitchers to make a few decent starts during the year, and if Reyes and Wainer are as good as we think they'll be, we reap the benefits in 2008-2011. I'll pay that price in a heartbeat.
by MdRedbirdFreak on Mar 26, 2007 3:53 PM EDT up reply actions
I agree on that point
Wainer's innings
Both Reyes and Wainwright are older than either of those two, (I believe both are 25 right now) and both have had more conditioning to the extended nature of the season at the pro level. Reyes was drafted in 2003, so this is his fourth full season as a pro, and Wainwright was drafted in, what, 99 or 2000? I think it was 2000, but I won't swear to it. Both of them have been at the professional level long enough to be much more used to the grind than either Verlander or Weaver. Verlander was drafted in 04, signed late, and only threw a handful of innings late that summer. Weaver was a very similar situation. Both of them were still trying to get acclimated to the length, and the grind, of pro ball. I think the Cards' two 'A's are in much better positions, neither one having been pushed to the bigs before they were ready.
Not that I don't think it's a concern, I just think that Adam and Anthony have definite advantages, just in terms of already having made more adjustments.
by the red baron on Mar 27, 2007 6:47 AM EDT up reply actions
Agreed.
I look at this as a sprinter turning into a marathoner. It takes a lot of time for the body to transition and get use to a lot of work every few days versus a little work daily. I hope he hold up, but...
If there were a starting pitcher DL pool, I would put my money on Looper first and then Reyes (a hunch).
Final thought, who are the 6th and 7th starters if a starter does go down?
6th and 7th starters
Put they are all just holding a spot for Mulder who should be back in August.
by Born in 82 on Mar 26, 2007 4:03 PM EDT up reply actions
IMPORTANT POINT
Thus, look at how many of Carpenter's starts come on the First game of a Series. Get ahead in that series, and you've got a better chance to take it. And then down the line, next best pitcher goes in 2nd game, so on and so on.
Obviously, might not be the biggest factor, but it is an important one.

It's still spring, it's still spring,
But man, am I excited about Kid W in the rotation. It may be just like cloning Carp, which I believe we were seriously suggesting at one point last season. ;) As with everyone else, I'm starved for the games to start counting, and I am THRILLED with Adam's performance today. Our rotation is leaps and bounds better without Marquis and an injured Mulder in it, and if we can avoid those devastating seven or eight-game losing streaks, we could be very, very good this year. :D

The offense seems to have seen a regression
Tony seems to be tinkering with the lineup as of late, putting Edmonds in the #2 spot and Duncan in the #5 spot. This gets Edmonds more pitches to hit, but really, at this stage: who do we want seeing more hittable pitches?
Perhaps it is just a ploy in ST to get Edmonds some looks since he has been on the shelf the entire time. That's reasonable.
I think the pitching should hold up quite well, however offensively, this team could be in serious trouble.

Beautifully written. I got goosebumps, too.
agreed on both
i have faith pujols will be a (deserving) all-star. but he hasn't been an all-star the past few years; he's been an mvp. it will be disappointing if he isn't that again. and rolen and the outfield really need to come through.
i've been bashing the pecota projections for our offense along with everyone else, but if we're just looking at the spring i would have to say they look a lot closer than i'd like.
I don't see how anyone can't be alittle

Maybe WPct isn't the best measure of leverage
Basically, my thought was that maybe the leverage numbers make more sense if you line up the pitchers against a team's projected runs scored. Won't explain Carp facing the Pirates 2/6 starts, though. But it might expain jumping through hoops to run him out against the Cubs an extra time or two, since their offense looks to be pretty solid.
