Howry's GB/FB/LD percentages are nearly identical to last season, yet he's on pace to give up roughly 1.5x as many HRs. That has been his main problem this season. Of course, those percentages aren't as good as they were a few years ago, but that's not terribly surprising: http://www.fangraphs.com/graphs/237_P_daily_full_9_20080721.png His K/BB is actually at a career best this season, as is his BB/9, yet his BABIP against is a career worst. I think he's been unlucky. There has been one other change, however. His fastball % has dropped from 10.4% and his slider % has increased 13.3% from last season.
