High 3/4 slot; brings front leg up high with knee tucked in; upper body tilts back; off-balanced; inconsistent with lower-half; stride gets long at times; good arm speed; finishes across his body; has trouble staying closed during release; decent athleticism; a little uncoordinated; when he has it all working the ball comes out easy with plus-plus velocity.
Bradenton Marauders (High A, Pirates)
60; #3 starter
Lacks consistent command; below-average at present; gets flat when thrown in the 95-96 range; tailing action in the 93-94 range; explosive pitch when located down; primary pitch first time through the order; leaves it over the plate too often; can be squared up when flat; overpowering when the command is on.
12/6 action; tight spinning; big drop pitch; has trouble with feel and staying on top; arm action slows down; flashes easy plus potential; solid out pitch; swing and miss generator; plays extremely well of fastball; does good job locating down; has confidence to throw in any count; effective to both LH and RH hitters.
Feel isn't there yet; floats it up there too often with little to no action; consistently flat, but does get good depth; lacks deception; arm and delivery slow down; good velo separation from fastball.
Sporting a workhorse frame, Glasnow has one of the highest ceilings around. Fastball command is really holding him back right now. When he's repeating his delivery, there aren't many arms out there who can overpower guys like he can. While there is concern with control and command, his delivery isn't a mess. This should be a problem that can be fixed with more experience and coaching.
His curveball is a second legitimate plus offering that should continue to become more consistent. When he's spinning it right, it's an absolute hammer that can generate swing and miss while also buckling knees and freeing hitters. The changeup needs the most work and refinement, but he's shown enough with it to where it will eventually become an average third offering. He has thrown a few sliders/cutters in the mid 80's, but has not shown it enough in any outing I've seen to grade it.
