Yeah, that's right, he has a K/BB ratio of 12 (24/2) this month. He's just stopped walking batters, and no, he's not getting hurt when he's been in the strike zone either.
Peavey is a four-pitch guy (fastball, curveball, slider and changeup). His fastball has mostly been sitting in the low 90s for Savannah. Pitching Coach Glen Abbott has been impressed by Peavey, and coming into this start, explained that he still had room for growth, "His stuff is pretty good. we haven't seen him yet when everything was working good for him."
In Peavey's previous outing, he gave up a personal season-high five runs, four in the first inning. talked about how Peavey has improved his pitch selection as the season has gone on. To Abbott, the issue was not pitch quality, but selection, "He got himself in trouble with pitch sequences. He got behind in the count with off-speed pitches." In general, Abbott is working with his young pitchers on varying their sequences and becoming more unpredictable. The coach explained that "the better time to repeat a breaking ball, with men on base, is after a ball, but most of the time, they [young pitchers] don't like to do that. They like to throw [the breaking ball] after a strike. That's so predictable. You throw a breaking ball, for a ball, here's the fastball."
Peavey has the potential to pitch in a Major League rotation, but it's still a long way from Savannah to Citi Field.
