The 17th round draft pick of the Texas Rangers in 2022, the 6-foot-3 slender-bodied lefty led the Florida JUCO ranks with 122 strikeouts last spring. From an over the top slot Dorsey produces swing/miss stuff with his low-90s riding fastball and a hard, sharp 79-81 mph curve.
6’3” 160 lbs. Long/athletic frame w/ projection FB up to 92 mph. Deceptive, getting on hitters late. SL flashed 1/7 shape w/ slurve action - swing/miss at 2405 rpm 6 K’s over 3 IP FB: 89-91 T92 SL: 77-78 CH: 80-81
Positional Profile: LHP - Long, loose arm that whips through the zone. Potential for added strength and velo in the near future.
Body: 6-foot-2, 150-pounds. Lanky frame with wiry limbs. Plenty room for added weight.
Delivery: Works up tempo with quick delivery and high leg kick.
Arm Action: LH. 3/4 slot. Long arm back and fast out front.
FB: T87, 83-86 mph. Natural arm side run. Tails off late.
CB: 64-70 mph. 11/5 shape. Has depth. Tunnels with other pitches when he's out front.
CH: 71-75 mph. Fades when down. Circle change action.
