Gavin
Hollowell

7-18-2018: 6’7/205 pounds with a long and lanky frame. Plenty of room for additional strength in upper and lower half. Significant physical projection remains. Pitches from a release with fast and loose arm action. Sinks on his backside a bit during delivery but maintains a level shoulder plane. Glove side extends out towards 3B after hand break; causes him to get too rotational at times. Throws with conviction but actions are smooth enough to be a starter. Flashed four pitches during his outing. Fastball comfortably sat 90-93 mph and topped at 94. Not much downward plane to the pitch but it has good life out of his hand. Curveball was 74-76 mph with 10-4 shape. More horizontal break to it than depth. SL was 79-82 mph; showed tighter spin and sharper break than CB. Good depth, especially when working to the back foot of left-handed hitters. Chaneup sat 83-84 mph with some late fade. It still needs refinement. Good feel for all of his offerings. More control than command but everything stays around the zone. Given his actions and frame, it’s easy to see Hollowell making significant strides in stuff and performance down the road. Had a fantastic season in 2017 for St. John’s out of the pen. Could stay in a relief role and repeat that success but making the transition to a starter shouldn’t be difficult for him. Either way, his future on the mound is bright and he has a high ceiling. (Dan Jurik)
