If you stayed up late enough last night, you know that Chris Davis delivered the Orioles' most recent walk-off heroics with an RBI single in the 13th inning against Boston.

His bloop base-hit against Red Sox reliever Alex Wilson came on a fastball, a pitch he's done plenty of damage against in his torrid start this season.


But there's actually another pitch that Davis punishes like none other -- the slider.

Buster Olney wrote this morning about the top pitchers and hitters by specific pitch.

Davis, according to the stats culled by one of ESPN's researchers, has an OPS of 1.624 against sliders, by far the best in the majors. (Angel Pagan is a distant second at 1.227, followed by Lance Berkman at 1.140.)

Davis ranks eighth against changeups (1.155 OPS), which may suggest that it doesn't make much sense to work him off-speed at all. But good luck challenging him with fastballs all day.

He does, for the record, lead the majors in total OPS (1.105).

J.J. Hardy is the only other Oriole in the top 10 facing a specific pitch, ranking fifth against curveballs (1.188).

None of the Orioles' pitchers rank in the top 10 for lowest OPS allowed with a specific pitch, according to Olney and ESPN's research.
