Roy Oswalt's Splits from Game Two

In last night's NLCS game (pitch log) between the San Francisco Giants and Philadelphia Phillies, Roy Oswalt's sinker, which is really a two-seam fastball, was quite effective. He threw it 45 times in 14 different plate appearances to a Giants line of .083/.214/.083 and a .167 wOBA. Here are the numbers on each of his pitches from last night:

Even more interesting was Oswalt's success against left-handed batters last night:

ISO.111.000.200
wOBA.197.103.279

Oswalt allowed NO hits to LHB. In fact, against his two-seamer, Giants LHB managed just one walk and struck out 5 times in 9 PA. Quite impressive given that lefty hitters managed a line of .299/.354/.483 against his two-seam fastball in 2010. Oswalt's only real mistake to a righty was the HR to Cody Ruth Babe Ross Cody Ross. But based on the way Ross has been swinging the bat in this series, it's nothing Roy should be ashamed of.

Comparing Oswalt's splits from game two to his 2010 numbers hammers home just how impressive he was against lefties last night:

Taking a look at Oswalt's pitch frequency to LHB last night gives us some more insight as to how he was so successful, as he effectively kept the ball away:

Buster Posey vs. Lowe's Sinker

Entering last night's game Buster Posey was one of MLB's top performers when facing the sinker ball. Of course it's no surprise Lowe relies on his sinker to get outs.

Derek Lowe's Pitch Log for Game 1 of the 2010 NLDS

Below you will find a heat map representation of Posey's SLG% against the sinker compared to the rest of Major League Baseball in 2010. When facing the sinker he is second in the league with a .775 SLG%. Only Paul Konerko has a higher SLG% when facing the sinker (.962). We should also note that Posey's AVG when facing the slider is .400 (6th in all MLB).

Meanwhile Posey struggles against the slider. Versus the slider in 2010 Posey has a SLG% of .397 (63rd percentile across MLB) and a AVG of .219.

All that said Derek Lowe still threw approximately the same number of sliders and sinkers to Posey (5 sinkers, 6 Sliders). Posey rarely swings at the first pitch resulting in  two first pitch sinkers for called strikes.
