Total Called Balls = 87; Missed Strike Calls = 14 (Click image to enlarge)

Now take a look at last season's list:

2011 All Starting Pitchers (min. 500 pitches thrown to PitchFX strike zone)Justin Masterson is the one name that has reappeared in the 2012 top ten list of squeezed starting pitchers.  His name shouldn't be a surprise - he's one of many sinker ball pitchers that made the top ten for the 2011 list.  The high and low parts of the strike zone are often the most difficult for umpires to call consistently correct since they change slightly batter by batter.

Expect to see more sinkerballers sneak their way into the 2012 list as the season progresses.
