2015 Splits in Review: Corey Oswalt

Corey Oswalt

The 2012 draft pick had a good full season debut with Savannah, and could be useful down the line for the Mets

RH SP, 22

2015 with Savannah: 23 GS, 128.2 IP, 4.13 RA/3.36 ERA/3.06 FIP/3.16 xFIP, 153 H, 59 R (48 ER), 99 K: 21 BB (18.3 K%: 3.9 BB%), .295/.327/.393, .355 BABIP*, .094 ISO, 104 wRC+ª, 69.6 LOB%, 0.42 HR/9, 89 ERA-/81 FIP-/83 xFIP-, 49.6 GB%: 21.7 FB%: 22.1 LD%: 6.6 PU%, 0.99 GO/AO, 6.7% HR/FB

*.422 BABIP allowed at home, .301 BABIP allowed on the road
ª104 wRC+ with the bases empty and with runners on base


            The Mets drafted Corey Oswalt out of Madison HS in San Diego with their 7th round pick in the 2012 draft aware that he was going to be a long-term project on the mound. He had mostly been a third baseman in high school, but he surged on the mound during his senior year, and former exec Paul DePodesta saw him a few times before the draft. The Mets took a chance on him, and Oswalt quickly gave up his commitment to play for UC Santa Barbara. Oswalt didn’t have a great debut season with Kingsport after signing, and then he missed most of 2013 battling injuries, but he finally broke through with a nice year for Brooklyn in 2014, which earned him a starter’s role with Savannah in 2015. He allowed a .355 BABIP last year, and I think that masks the quality of his season. He induced groundballs at nearly a 50% rate, only walked 4% of batters faced, and maintained an average strikeout rate, so it was actually a pretty good year for the righty. Below I take a look at some of the trends from his 2015 splits and then share GIF’s from the 5 MiLB.tv starts I caught last year.

            Oswalt became a more effective pitcher for Savannah as the season went on, and then finished the season red hot over his final 6 starts: 32 IP, 1.69 ERA, 30 H, 23.2 K%: 0.8 BB%. He sits about 88-92 MPH with his fastball – both the four-seamer and the two-seamer, which is the more common pitch. He also mixes in a changeup, slider, and curveball, and can throw all 4 pitches for strikes with consistency. The changeup is currently his second best pitch, showing a nice sinking and fading action, and flashing above average potential. I think his changeup likely played a role in his success against LHB’s last year, as he struck LHB’s out more often than RHB’s, and induced a 57% groundball rate from them. His breaking pitches show usefulness, but project to max out as average pitches. They fit his plan when he can keep them down, but become BP when left up.

            His BABIP allowed was high throughout the game, but he didn’t take a big hit in effectiveness until his third time through. When I saw him, he had trouble keeping his stuff down later in the game, and 88 MPH belt-high fastballs get crushed at all levels – the homerun he allowed on 7/11 was on a meatball in the 6th inning. From Table 3, Oswalt’s BABIP allowed on groundballs was much higher than the SAL average, so I calculated his expected BABIP, and it’s ~.330. He still would’ve allowed more than a hit per inning at that rate, but he also would’ve held SAL batters to below league average production.
            If Oswalt’s breaking stuff sharpens up, he should be able to stick as a starter with back of the rotation upside – think Dillon Gee, if all goes right. If not, he’ll need to move to the bullpen, but his sinker-changeup combo and success against lefties will make him a potentially useful option – think Miguel Socolovich, if all goes right. He allowed 10.7 H/9-innings last year, so his overall stat line immediately causes hesitation, but he didn’t allow a lot of hard contact in the starts I saw – to be fair, 4/5 below were among his best starts all year. The rate stats not BABIP dependent were average (K%) or better (BB%, GB%, HR/9) for the season, and that matches the pitcher I saw on MiLB.tv. I think Oswalt is currently a little overlooked in the system, but that could easily change with a similar season put up at the FSL this year. He’s not the high upside guy #MetsTwitter goes nuts for, but I think he’s a high floor guy who can be useful to the Mets down the line – think mid-2018, if all goes right.
