MASH Report (5/15/14)
• I hate to see Jose Fernandez needing Tommy John surgery (TJS). His owners really should not have been totally surprised the injury happened. While it is impossible to predict exactly which pitchers will get injured when, Fernandez had some injury risk signs coming into the season.
1. He threw hard. When Matt Harvey had TJS last season, I looked at extreme hard throwers to see if they have more injury risk. Among only 15 starters, there was a heightened risk. I would hate to draw too many conclusions from a sample of 15, but the trend continues.
2. He threw a ton of curve balls. Over 30% in 2013 and in 2014. Previously, I found pitchers who throw their curve more than 25% of the time have a 50% chance of going on the DL.
3. He hadn’t yet established himself in the majors. Pitchers who have been able to make in the majors for three complete season are about 10% points less likely to be DL bound.
All three factors put Fernandez at a higher than normal injury risk.
