Interesting topic. I suspect that as hard throwers are generally good for more innings than soft tossers. Not to say its wise to push the limit with anyone but I would expect Duffey and other fireballers to fare better than guys like Shibuya and Rogers.
That sounds about right. Weaver gets by on extreme rise with his fastball and extreme crossfire action combined with extreme extension and some pretty nasty breaking stuff too. Interesting formula, really.
Swarzie technically throws a changeup but like just about everyone else on the staff he can't really lean on his 3rd pitch to help him get through lineups 3 times or more.
His release point has changed. It coincides pretty well with the decline. http://www.brooksbaseball.net/plot_bytime.php?s_type=2&time=month&player=539438&b_hand=-1&gFilt=&pFilt=FA%7CSI%7CFC%7CCU%7CSL%7CCS%7CKN%7CCH%7CFS%7CSB&startDate=03/30/2007&endDate=07/23/2013&minmax=ci&var=z0 http://www.brooksbaseball.net/plot_bytime.php?s_type=2&time=month&player=539438&b_hand=-1&gFilt=&pFilt=FA%7CSI%7CFC%7CCU%7CSL%7CCS%7CKN%7CCH%7CFS%7CSB&startDate=03/30/2007&endDate=07/23/2013&minmax=ci&var=x0 Might be he's changed his delivery to compensate for the elbow. Less over the top. Might be he's changed spots on the rubber too.
