Good start for Hall.
Stuff:
Fastball: 94-98, lots of swings and misses
Slider: 86-88, probably the pitch he can throw for strikes most consistently. Pretty flat but good horizontal movement for good back door pitch against right-handers. Decent left on left pitch.
Change: 86-87, got some swings and misses and able to throw for some strikes, but he wasn't commanding it well. Note, he shook off Nottingham in his 4th inning on a 3-2 count and wanted to throw the change. he missed high with the pitch, but it shows he's trying to improve the pitch and wasn't worried about the walk.
Curve: 82, was his least used pitch and buries it in the dirt a bit too much. Good vertical and decent horizontal movement though.
Pitches quickly when he gets on the rubber but seems to go to the rosin bag, dirt on the mound, or cleans his spikes after every pitch. Not afraid to shake off catcher, but did not always execute the pitch he wanted to throw. Very athletic guy getting off the mound. Good quick accurate pick off throw.
Pros: Obvious he's a 4-pitch guy who is extremely tough to hit. Not a comfortable at bat for either righties or lefties. The stuff is legit.
Cons: Took him 78-pitches to get through 4 innings and that has to improve. He gets in deep counts on almost everyone and still throws too many uncompetitive pitches.
Assessment: Needs more time in the minors to work on the command if he's going to be a starter. He can pitch in relief right now no doubt. Probably would throw consistently 100 mph as a reliever, but he's got a starter's repertoire so he needs to stay there.
