He was all over the place last year, but I looked on Baseball Savant at his outing today. The velo was sitting 93-94, which is usual. The spin on all his pitches were up about 1000 rpm last year in MLB compared to 2022, possibly due to only pitching out of the pen last year.
Last night's game his fb spin was still up to 2023 levels, but the spin on his curve and cutter were up a bit and the spin on his sweeper was way up to almost 3000 rpm, up from 2700 in 2022 and 2800 in 2023. It would put him in the top 10 in the MLB. Not sure if stuff & velo is still the issue for him, maybe just the command. But i didn't look at pitch movement. Wesneski's sweeper spinrate is far lower, around 2600, but his active spin is much higher.
