Jordyn Guilderson: OF/LHP, (2026) Quabbin Regional, MA. 5-foot-1, 110-pound slim frame. Raw at the plate, the left-handed hitter's best exit velocity was 58 mph. (46.0 mph bat speed average). (13.2 mph hand speed average). Began in a balanced athletic stance with a tight load, then used a small stride. Had a long swing plane, developing bat speed and level finish. Found a couple of barrels through his round. Base hit approach. Raw from the outfield, his best throws to the bases were registered at 65 mph; had a developing natural exchange, developing hands, and developing footwork. Fields the ball out front, movements laterally were raw developing. Used a consistent arm action and a high ¾ slot. In the 60-yard dash, recorded a time of 7.68. Raw on the mound, used low ¾ arm angle and a consistent arm action while showing developing arm speed. Feel type pitcher and used some effort. Showed consistent balance point and in line shoulders. Lands closed with a falling off finish. Threw his fastball 59-60 mph; has control arm side around the zone and running action. (Max spin 1698; Avg 1605). Throws a straight changeup (57-58).
