Uncommitted 2025 RHP/3B Logan Diffey put together a good performance at the Ottawa/Gatineau New Year Invite and is an arm that college coaches need to be on within the senior class. Size and plenty to project on at 6-foot-2, 140-pounds and it’s a long, loose arm that was able to land all three pitches for strikes. The Watson Elite right-hander sat 82-83mph (2480+), along with a two-plane breaking ball at 71-72mph, slider at 72-75mph and splitter at 74-78mph. Overall, there was plenty to like in the bullpen and should be plenty of strength on the way. With the bat, the left-handed hitter generated a peak exit velocity of 86.5mph and peak distance of 281ft.
