One of the missions of Jim Tracy this spring was to coax better performances out the Colorado hitters with two strikes. At either end of the Rockies spectrum were Ryan Spilborghs and Ian Stewart. Ryan ranked 21 out of 343 batters with a .309 wOBA with two strikes in 2010. He accomplished this by keeping his plate discipline in the situation:
Except for pitches on the low corners, Spilborghs did a good job of recognizing pitches, swinging at strikes and taking balls.
Ian posted a .156 wOBA with two strikes, 335th on the list.
So Steward goes fishing a lot farther outside than Spilborghs, and takes way too much on the inside part of the plate. Few batters are going to hit well with two strikes, but there's no reason to be as weak as Stewart in that situation.
