I stumbled across what I thought was an intersting article about the former pitcher Mike Marshall and his pitching research center in Florida. Here is the link:
There doesn't seem to be any video of the motion they describe, but it did get me thinking about what changes may or may not evolve in the future. Take a look at Marshall's stats at the bottom of the article. As a RELIEF pitcher in 1974 he logged 208 innings in 106 appearances with a 2.42 ERA! I know the game has changed and I'm not saying that Marshall has the answer to pitching durability, but I wonder how much time and money MLB teams spend on studying/teaching pitching mechanics. My perception is that pitchers were more durable 30+ years ago, but has anyone seen a statistical study comparing the generations? Maybe Walt needs to send some scouts down there and find us some arms!
