Physical Description: Thicker build with muscle throughout the frame at present. Proportional body with wide shoulders and long arms. Moderate athleticism; won't wow you, but not stiff either. Little room left for projection. Solid arm speed.
Mechanics: Full windup; drop and drive delivery that he moves through quickly with high effort. Feels rushed at times, lots of moving parts that create some deception. The pace has ticked up quite a bit from his college days where he was more deliberate through the rock step and leg lift; the leg lift is more muted now, too. Plant leg starts pre-set; longer arm action that drops down the body and comes through at a 3/4s slot. Intense and aggressive on the mound with significant head-whack at times -- has a late-inning reliever feel. Repeats better after he settles in. Works from the very end of the 3B side of the rubber.
Fastball: 92-96, T97; some run and good carry -- carry feels especially good for the arm slot. Can overpower hitters with it in the zone, jumps out of the hand. Plays up even more after hitters have seen the change - they're almost always late and swing through it or pop it up. Grade: 55
Curveball: 72-74; 1-7 shape with good depth. Flashes good bite, but rolls far more often. Clear 4th offering, used much more sparingly. More of a show-me pitch to steal a strike than a weapon. Grade: 40
Slider: 83-86; Sweeper slider with 2-8 shape. Flashes late bite that really fools hitters. Locates off the plate gloveside often; will try to drop it into the top of the zone but gets punished when the hitter isn't fooled. Grade: 45
Changeup: 85-87; solid tumble with solid but inconsistent fade. Sells well with armspeed; typically locates down armside, but will leave it up once in a while. Tunnels well with the fastball and falls off the table. True swing and miss offering and probably his best pitch. Shown mostly to righties, but the depth and deception make it a legitimate out pitch against all hitters. Grade: 60
Control and Command: Solid strike thrower but has times where he loses the release and can't find the zone. Can nibble too much with 2 strikes - struggles to put lefties away when the slider isn't biting. Knows how to set pitches up but doesn't always hit his spots to be effective. Appears to be limiting the walks a bit better after having trouble early on in 2021. Control: 50 | Command: 45
Overall: Hard-throwing lefty with a solid 4-pitch arsenal. Plus changeup is the headliner with a fastball with good carry that's touched 97 this year. Has a slider and curve that he uses as well, but pitches are a full step behind the fastball and change. Seymour is a solid strike thrower with some decent pitchability that gives him a very real chance to start, however, the delivery has a lot of effort and significant head-whack; the Rays have used him in short 3-4 inning spurts so far during his first pro season. Seymour could realistically be a five-and-dive 4th or 5th starter, but the intensity of the mechanics make me lean toward a multi-inning reliever. He'll need to develop a better weapon to put lefties away to maximize his potential. High floor arm who seems like a lock to be a big leaguer.
