Kentucky freshman Toby Peterson is a left-handed arm with real upside, but still an early-career work in progress
Peterson is a 6'2", 185-pound freshman LHP/UT at Kentucky who entered college with respectable prep pedigree — including a Perfect Game national ranking and a fastball that touched 89 mph — but his early 2026 college numbers have been rough, with a 21.60 ERA and 2 strikeouts in 1.2 innings. He looks like a developmental arm rather than an instant-impact piece, which means his appeal is in projection, left-handed versatility, and long-term ceiling more than current production.
