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.
