Weaver’s changeup returned a 34.5% whiff rate, his best pitch in that respect. It was excellent at getting hitters to expand the zone, evidenced by a 43.2% chase rate. The change limited hitters to just a .169 batting average and .273 xwOBA.

A distant fourth pitch, Weaver’s curve features more of a 12-6 shape. He didn’t show particularly great control of the pitch, as it notched just a 28.1% zone rate. And it’s not much of a chase pitch either (24.6%). It remains a work in progress.

Weaver’s fastball has slightly above-average spin (57th percentile) and averaged just under 94 mph. It returned a modest 8% swinging-strike rate while holding hitters to reasonable .328 xwOBA.

Weaver’s four-seam fastball is about everage. There’s some pop to it but not much. Hitters don’t exactly struggle against it, though I’ve certainly seen much worse. He leans on it most—just like most other pitchers—but with how he throws his cutter he may way to dial that back a smidge.

Weaver gets sufficient depth and run on his changeup. Location isn’t necessarily the problem, either. He strikes a lot of guys out with it. It’s not a bad pitch, but it can be a lot better. He just throws it too hard. On average, it’s only two miles per hour slower than hit cutter.

HItters will freeze on Weaver’s curveball from time to time, but not often enough. Hitters batted over .300 against it, with a BABIP in the same realm. There’s potential, but at some point that’s not enough.

Weaver’s cutter has some late bite to it. Not enough to get a lot of whiffs, but enough to generate weak contact on a fairly consistent basis. He also doesn’t throw it that hard. In 2018 it was almost 7 mph slower than his fastball.
