I think you are confusing this Trackman system with plain Pitch/FX (which mainly tracks the pitch and not the pitcher's full mechanics) and thus selling it short. The ESPN magazine article on it focused on its ability to quantify a pitcher's mechanics, and the consistency/repeatability of those mechanics. It's still a young system, so you'd have to build up your data set, but I could easily see that being helpful in identifying quality pitchers (and the best roles for pitchers -- how much does a guy's mechanics change after X number of pitches?). And while it's not going to predict injuries, mechanics repeatability is thought to be a pretty big factor in a pitcher's injury potential -- quantifying it would be a huge help. Remember, the Twins weren't even relying much on pre-draft medical info until recently -- they could use all the help they can get! Also, the whole Trackman system is now small and portable, meaning it could be set up anywhere by scouts or coaches and used to analyze potential amateur and international prospects. So it gives you Pitch/FX-type capability everywhere, for any pitcher, and adds mechanics analysis on top of that. Find a guy somewhere with similar mechanics and pitch movement as Glen Perkins and you've really found something, regardless of his stats or if he's even pitched much before. I pretty much agree that metrics like WAR, FIP, etc. aren't exactly huge helps over other previously available stats, and they don't do anything for amateur prospects. That's why the place to look is proprietary technology, behind the scenes -- I can even imagine a system similar to the above to analyze a batter's swing. Find an amateur with a repeatable swing like Joe Mauer's and you may have a prospect on your hands, regardless of his stats. 17 MLB teams are using Trackman on pitchers, and I'm sure some of those are also working on new technologies too. There's really no reason the Twins shouldn't be one of those. EDIT TO ADD: And if the Twins are or become one of those, they should be disclosing that fact to fans as much as possible. Keep the proprietary info close to your vest, of course, but tell the fans you're striving to find new ways to get better, faster. And for heaven's sake, manage the PR better than the Jack Goin "stats guy" nonsense.
