RHP Mason Palmer (Warren, 2027) provided an interesting look on the mound. He stands in a wiry, long-levered 6-foot-1, 181-pound frame with seemingly more room for added strength in the frame. Palmer showed a clean and whippy arm out of a low ¾ slot, with his fastball sitting 83-84 mph with heavy arm-side movement. He turned to a slider that sat 71-73 mph with sweeping shape that averaged 2422 rpm, and a change-up at 74-76 mph with fade.
Positional Profile: RHP
Body: 6-1, 178.6-pounds. Wiry, loose-levered build.
Delivery: Stretch-only delivery, high leg lift with tuck, tall/fall down the mound.
Arm Action: RH. Long, whippy arm arm action, low 3/4 slot.
FB: T84, 83-84 mph. Plays with arm-side action. T1790, 1634 average rpm.
SL: 71-73 mph. Sweeping, horizontal shape. T2538, 2422 average rpm.
CH: 74-76 mph. Throws with intent, plays with fade. T1498, 1430 average rpm.
