Thornton was a two-year JuCo performer at Barton Community College in his home state of Kansas before jumping to Grand Canyon as a junior in 2023, mixing in stops in the Appalachian and MLB Draft Leagues in between. While scouts came to see teammates Jacob Wilson and Homer Bush Jr., the southpaw dominated on the bump and slid up to the fifth round to the Mets, signing for just under slot at $350,000. He was a solid performer at two A-ball levels in his first full season and has climbed to Double-A as a full-time starter, albeit one slowed by an oblique injury.
The 6-foot-3 left-hander has a deep arsenal without anything that truly pops off the page individually. His fastball touches 95 mph occasionally but generally sits 89-92. He can mix in both a four- and two-seamer to vary up the looks. His best pitch is an 83-86 mph slider -- a two-plane breaker that he can spot on a dime. He plays off that with an upper-80s cutter that hitters will chase outside of the zone. An 82-84 mph changeup and 75-77 mph curveball round out the arsenal.
The diversity of Thornton’s repertoire keeps hitters guessing, and with his loose, athletic delivery and an attack mentality, he can keep pouring in strikes, rarely putting himself behind in the count. That will remain his biggest strength as he works toward Queens. Thornton’s ceiling might be limited, but with his near-elite control, he won’t get in his own way of being a potential No. 5 starter.

Thornton spent two years at Barton Community College and was one of the better junior college players to transfer to a Division I program after logging some summer innings in both the Appalachian and Draft Leagues. He’s been a mainstay in Grand Canyon’s weekend rotation and has been a steady performer, no doubt benefitting from extra looks with scouts coming in to see teammates Jacob Wilson and Homer Bush Jr.
While none of Thornton’s individual pitches jump off the page, he has a full repertoire and a good idea of how to use it. His fastball tops out at 93-94 mph and averages around 89-90, but he commands it well. His breaking stuff doesn’t have a ton of bite, but he can add and subtract from it and lands it all for strikes. His 80-mph changeup plays nicely off of his fastball-breaking ball combination.
Without a true out pitch, Thornton’s ceiling is limited to that of a back-end starter, but he never hurts himself with walks and manages to keep hitters off-balance enough to miss a good amount of bats. Athletic on the mound, he’s the type of steady left-handed college starter who invariably gets taken on Day 2 of the Draft.
