Pitcher A: 13-1 record, 101.1 IP, 1.15 ERA
Pitcher B: 4-5 record, 83 IP, 4.55 ERA
Click through for the answers.Both are Ubaldo Jimenez. Pitcher A was his performance from the start of the season through his June 17th start against the Twins. Pitcher B was his performance since then, starting with his June 23rd game against the Red Sox and continuing through his Sept 1 game against the Giants.
What's interesting is that a lot of his peripherals haven't changed. Keeping the same time periods:
Pitcher A: 5.8 H/9, 7.8 K/9, 3.2 BB/9
Pitcher B: 7.5 H/9, 8.9 K/9, 3.9 BB/9
So he's allowed about 35% more hits, and his K's and BB's are both up in the neighborhood of 15-20%.
Neil pointed out that it's his BAbip that his really changed, up from .245 to .299. This is consistent with the increase in hits.
