Physical Description: Tall righty with long limbs and broad shoulders. Thick thighs, average butt; upper half has room for some good weight, but doesn't look underdeveloped. Live arm.

Delivery & Mechanics: Three quarters arm slot, mostly, will lean a little and move to a high three quarter at times - perhaps when he's working glove side. Moderate effort in delivery, a tick more from the stretch. Windup is casual with an easy leg kick to the navel before ripping his arm to the plate. Heavy followthrough as his leg swings around, pulls him 1st base side occasionally. Could see the lurch to the plate causing command issues.

Fastball: 92-95 with visible tail; has touched 98. Gets whiffs and pop-ups up in the zone, so it has some ride despite the lower arm slot. Uses early and often, out pitch for Ks. Grade: 60

Slider: 84-87, has decent movement but lacks any real bite. Slurvy, in between shape. Seems to lack feel and doesn't get a ton of whiffs or chase. Will try and steal strikes with it early. Grade: 50

Changeup: 83-86 with good depth. Sells with armspeed and gets swing and miss when it looks like a strike. Struggles to control it. Grade: 45

Control and Command: Below average. Misses in bunches and then has to come into the heart of the plate. This is a significant issue for him and will likely limit him to the pen unless the team can help him make an adjustment. Control: 40 | Command: 30

Overall: Starter's frame and arsenal with a reliever's control and command. The fastball is plus but the secondaries are fringy. Even if they improve, the command is still a limiting factor. High upside, high floor type pitcher who has a shot at being a backend starter and is almost a lock to be a big league bullpen arm.
