Padilla’s Fastballs
Yesterday, Dave C. noted Vicente Padilla‘s extreme platoon splits and how he matches up poorly against a lefty-heavy Philly team. I wanted to expand on this with a pitchf/x look at the issue.
As Dave noted, Padilla throws a ton of fastballs. He is fourth among starters behind sinker ball specialists Aaron Cook, Mike Pelfrey and Rick Porcello, in fastball percentage at 75%. Fastballs, on a pitch-by-pitch basis, show a large platoon split. So a pitcher with lots of fastballs should show an more extreme split. Curveballs and changeups generally show little platoon split. Padilla throws a splitter/changeup and a curveball, but he does so rarely and they are poor (changeup/spiltter) or average (curveball) pitches.
Padilla throws both a two-seam fastball and four-seam fastball. To RHBs, he throws the four-seam 35% of the time and two-seam 45% of the time, so to RHBs he throws fastballs 80% of the time. To lefties, he goes 55% four-seam and 16% two-seam. This makes sense: of fastballs, two-seamers have a larger platoon split, so it would be better to throw them more to RHBs and limit them against LHBs.
I plotted the location of all of this fastballs (green four-seam and blue two-seam) to LHBs and RHBs this year. The figures are messy, but should give a general idea of the location he goes with the two pitches.
To righties, you can see a kind of diagonal orientation of his two-seam fastballs running from up-and-in through the center of the zone to down-and-away. This is good: within the zone, pitches do best up-and-in and down-and-away. His two-seam to RHBs is thrown regularly to these locations. With his four-seam he mostly stays away.
To LHBs, the orientation of his two-seam would be opposite of ideal, where hitters do better. Because of this, he does not throw it as often and there is no general trend to where it ends up. He is left throwing his four-seam fastball much more, concentrating it on the outside half.
The differences are seen in the value of the pitches. Both of the fastballs are good to RHBs (0.4 runs above average for his four-seam and 0.7 for his two-seam), but against LHBs things fall apart (0.8 runs below average for the the four-seam and a horrid 2.5 runs below average for the two-seam).
As Dave noted, this is a really questionable call against a team with some good lefties.

Under/Over?: Padilla lasting 3 innings
Over
Over, but he still gives up 3 runs in the first 3, and probably should be pulled after 3, but Torre leaves him in. Then, once the game is completely out of hand in the 5th (say 5 runs in and 2 on and 1 out), Torre finally brings in Billingsley. Billingsley then gives them 2 2/3 IP with hardly a hit. But the Dodgers still lose 6-3. It will be poetic.
or not
Interesting stuff – really gives me something to watch for in the game this afternoon (and that is why I love good stat-oriented sites: they add depth and help me appreciate the game so much more.)
Padilla does throw a changeup/splitter. It comes in in the low 80′s, although he throws it under 10% of the time.
Good point. Thanks for bringing this up.
And despite all this evidence and everyone’s disparaging remarks, what does he do?
7.1 innings of one-run ball. Not that I like the man or anything, but..
Can you start making disparaging remarks about Billingsley? We can only hope….
Padilla, since being acquired by the Dodgers (regular season and playoffs)
53.2 IP, 15 ER, 44 H, 14 BB, 48 K
Interesting analysis, both posts. Too bad they couldn’t have been more wrong. Padilla pitched great.
/not trying to sound like a douchebag, I swear
The biggest thing I have seen from Padilla since he joined the Dodgers is that he just seems to be throwing hard more often. Before, he would live in the low 90s and dial it up sometimes. With the Dodgers, he seems to just be chucking everything at 95-98. Also, it would be great if he threw that crazy slow curve he made Victorino look stupid with more often.
Was he throwing a slider? It seemed like a lot of those strikeouts came on a breaking ball around 88 and with tilt.
I think that pitch is more of a cutter. Similar action though
still, i don’t remember anyone saying he had a fourth pitch. I doubt its always gonna be that good, but still. He got a lot of guys looking stupid with it. Did he learn it when he came to LA?
yeah, throwing close to 90% FB–sitting 94-96, with late movement–if you can do that, one pitch is all you need.
i think Padilla prefers highballs
Can we get an analysis of Padilla’s start on Sat.?
ya that would be great!!
like what he did to get the leftys that hes been horrible in his career against out with and stuff.. he was throwing 97 in the 8th inning!!!!! with a great cutter slider i never knew he had… and a 55 MPH CURVE that got a Swing and miss!
That pitch even had Victorino laughing. It was basically an Eephus. Even if Shane made contact, I don’t think the ball would have gone very far.
