Wilson showed a 3 pitch mix last night: FA (62), SL (13), CH (12). As per EL's latest in person report, Wilson pounded the upper half of the zone with his FA to good effect.
FA: 95.1 mph (Grade 58.5), 4.9" HMov (Grade 48.6), 8.6" VMov (Grade 46.0)
In EL's latest report he said, "touched 97 several times last night and sat 93-95 late in the outing. He pounded the zone with his fastball (72 of 98 pitches were for strikes) and blew it past several hitters up above the strike zone". He was 100% spot on. This is plus velocity with just enough movement to keep it from being flat, resulting in a 55/60 pitch that plays as a 60 when located up like it was last night.
SL: 82.7 mph (Grade 41.8), 3.2" HMov (Grade 53.6), -0.2" VMov (Grade 58.4)
EL said, "His slider flashes plus but is mostly average and is only capable of missing bats when it’s out of the zone". It showed as a 55 last night.
CH: 8.3 mph delta (Grade 52.7), 9.4" HMov (Grade 62.2), 2.7" VMov (Grade 58.9)
According to EL, "Wilson’s changeup is fringey and firm, without much bat-missing movement, but the velocity separation off of the fastball is enough to keep hitters from squaring it up, and it’s going to be an effective pitch". I agree with the part about it being an effective pitch, but I disagree with the part about it not having movement. The CH objectively has plus movement, and grades out as a 55/60 pitch overall.
Command: EL wrote, "Wilson’s delivery is much more graceful and fluid than it was when he was in high school, when scouts thought it would impact his ability to command the fastball and possibly move him to the bullpen". We saw him walk 3 in 5 IP, which is certainly not ideal, but we also saw him continually pound the upper portion of the zone with the FA. His 32.2% Zone% is below MLB average of 43%, so I agree with FG's assessment of 45 for his present control grade.
So we have a 20 year old arm with a 55/60 FA, 55 SL, 55/60 CH, and just enough control to make it all work. That's a solid #4 that produces 2+ wins annually who climbs the ladder as his control improves. His young age and rapid improvement at the MiLB level suggests average control is well within reason, which would make him a nice #3 while the plus velocity allows him to work up in the zone.
I think that's the deal with Wilson...as soon as the velocity declines enough that the FA can't work up in the zone, he is likely a back end or AAAA SP. He is almost completely reliant on beating batters up in the zone with that plus velocity, and without it he's basically Sims/Wisler. I would suggest not extending him, and looking to trade him the moment signs of velocity loss appear.
