Mason
Lei

RHP Mason Lei (Freeport, 2023) is an intriguing arm to keep tabs on this coming spring. The long-limbed 6-foot-2, 170-pound right-hander is easy to dream on with his highly projectable frame and fluid moving arm. Down the mound, Lei works with an athletic drop/drive lower half to stride in-line with the plate, landing with a slightly closed front foot before transitioning into an over-the-top slot. His fastball reaches the plate at a tough angle due to his arm slot, topping out at 84.0 mph, sitting mainly 80-83. He then went to a 12/6 downer breaking ball to pair off his fastball, showing depth and kept down in accordance with the zone at 63-64 mph. Lei then ripped off sliders at 66-67 mph, possessing short 10/4 shape and adding yet another quality offering to pair off his fastball. Last and definitely not least, the right-hander featured a changeup that sat mostly 71-72 mph, maintaining near-fastball arm speed while keeping it down in the zone, flashing heavy arm-side sink at times.
