From BA: 

Parker was a high-profile projection righthander out of The Woodlands (Texas) Christian Academy in the 2021 class. He was viewed as a tough sign and went undrafted and has pitched as both a starter and reliever for TCU in 2022 and 2024, though his 2023 season was lost to injury. In his 2024 season Parker posted a 4.11 ERA in 35 innings with a 27.3% strikeout rate and 13.0% walk rate. He throws a 93-94 mph fastball that touches 97 with above-average cutting life and pairs the pitch with a true cutter around 90 mph that occasionally blends into more of a slider look as well as an upper-70s slurvy curveball and rarely used mid-80s changeup that has significant arm-side life. Nothing in Parker’s mix comes in straight but his below-average control could limit his upside and keep him in the bullpen full-time in pro ball.
