+ '26 LHP Jacob Erb (Homestead) was another junior arm that walked away as a winner. A sturdy-bodied, 6-foot-3, 215 pounder - Erb showed positive development trends that are encouraging, a plus 3-4 mph tick compared to his bullpen at the same event last year. Erb pitched with a lower intent level, showing a simple, repeatable leg-lift delivery that is paired with a shorter, loose arm action. The southpaw pitched in the low-80s and touched 84. His secondaries, specifically his breaking ball, showed good shape and he was able to manipulate it on occasion. Erb also showed a change at 66-68 that played with over a foot of arm-side fade.
