Scouting Carson Fulmer and Other White Sox Prospects
Carson Fulmer was perhaps the 2015 draft’s most polarizing prospect. He was, on one hand, a college prospect with a career-long track record of success (sub-2 ERAs as a sophomore and junior, 167 Ks in 127.2 IP in ’15) and objectively hellacious stuff, while, on the other hand, both inefficient and the owner of an ugly-duckling delivery that scared off many more scouts than just the usual cross section of xenophobes. Mostly, three camps formed: the group that thought Fulmer could start, the group who thought he’d end up in relief and was bothered enough by that to move him down their board, and the group that thought he’d end up in relief but didn’t care.
In an ironic twist best suited for baseball, Fulmer has essentially proven each camp right while simultaneously remaining difficult to project, even as he’s ascended to the majors. His stuff remains incredible, each offering in the four-pitch repertoire ready to miss major-league bats, but he’s walked 51 hitters in 87 innings this season.
I like, in these call-up pieces, to talk about things like pitch sequencing and pitch utility so we can have a deeper and more intricate understanding of how these guys are getting outs. With Fulmer, that’s not possible. Because Fulmer is just as likely to throw a strike with his fastball as he is with any other pitch, he’ll throw any of his four pitches in any count to both left- and right-handed hitters. This is strangely liberating. Fulmer’s fastball was 93-94 mph at the Futures Game and in his debut on Sunday. All the secondaries (cutter 89-91, curveball 77-81 with 11-5 movement, changeup 85-89 with arm-side run) are above-average to plus and could be coming at any time.
Fulmer’s delivery is paced like a hummingbird’s heart beat and lots of scouts think it’s the primary cause of his wildness. It’s also part of what makes him so unique and difficult to hit. It appears as though the White Sox plan on using Fulmer in an upscaled relief role, which is probably going to be good for (a) maximizing his impact on the club this year by frequently deploying him for more than three outs at a time and (b) giving him more opportunities to hone his command than he’d be getting as a standard, one-inning reliever. It’s hard to project better than 40 future control for Fulmer, but there is a chance he figures out how to throw an acceptable amount of strikes sometime during his mid-20s — the way it looks like Trevor Bauer has, for example — and makes it work as a starter. If he does his stuff is good enough to carry him to a #3 starter’s value despite his likely inefficiency.
