Bay Area World Series Underclass (6/4/21-6/6/21)
Offensive notes: Balanced, even hands with high back elbow. Backside gets through with direct hands carrying on body. Best swings got sliced liners to RCF. Can learn to keep hands behind hips more consistently. 60-yard - 7.69 / EV mph - 74
Defensive notes: Higher actions on pops and longer arm action. Throws from a slinger slot and put throws around the bag, letting the MIF make a play. C mph - 70 / Pops - 2.22-2.34
Pitching notes: Simple delivery with controlled actions. Small rock at top of balance point and utilized a high glove side. Soft front side into ground while utilizing H-3/4 release. FB cuts and sinks to glove side and arm side. CB 11/5 with loose spin break; times where it was more sweepy. CHG arm side bottom.
