| Summary: Sheerin brings one of the louder pure arm profiles in the LSU program, headlined by a fastball that consistently sits in the mid-90s and climbs higher with real ride when he stays on top of it. The heater plays best above the zone, where the carry and angle generate uncomfortable swings, and it sets up a mid-80s slider that shows legitimate bat-miss traits with tight rotation and two-plane tilt. When synced, the fastball/slider pairing can overwhelm hitters in short bursts, and the whiff rates back up the visual impact. A knee injury wiped out his 2025 season, but post-injury looks, including Cape action, showed the raw stuff returning intact. Questions remain regarding command and overall strike efficiency. The delivery is aggressive and powerful from a lower three-quarters slot, but timing can drift, leading to scattered misses and inconsistent release. Secondary depth beyond the slider is still forming, with curveball and changeup more developmental than reliable weapons at this stage. The physicality and arm strength point to impact potential, but the outcome range remains wide: if the strike throwing stabilizes and a third pitch firms up, there’s a path to a rotation role; if not, the fastball/slider combo profiles cleanly in a high-leverage relief lane where the power could play quickly. | |||||||||||
