5-foot-10, 170-pound switch-hitting catcher, proportional build, strong frame, continues to add to frame with more to come as he physically matures, ran a 7.29 laser-timed 60. Offensively, wide base, hands start near center of body and load back smoothly, good balance on finish. Swing works short to the zone, level through from both sides of the plate, displayed a similar gap-to-gap approach, can drive the ball from the left and right, 91 exit velocity off a tee. Defensively, short, quick arm, quick to release from an over-the-top slot, kept throws low on the target, 74 out of the crouch. Flexible in the hips, soft receiver, quick on transfers allowing for him to get the ball out in a hurry, clean footwork, pop times ranged 2.00-2.10.
5-foot-9, 170-pound switch-hitting catcher, stocky build with strength, still has a ways to go before he has reached physical maturity. Offensively, has feel in the box, slightly open setup, hands start low and smoothly load back and up, short stride to square, good balance throughout. Has easy effort in his swing, barrel works mostly level with extension through the zone, strong wrists/forearms allow for him to drive the ball to all fields. Showed a good approach at the plate with situational awareness, rarely plays outside of himself, consistently finds barrels. Presently a mostly line drive hitter, with continued physical development will add more power to his swing.
