The St. Louis Cardinals’ 2025 season saw the arrival of highly-touted prospect Liam Doyle. He wasted no time making an impact. The left-handed pitcher selected fifth overall in the 2025 MLB Draft, has swiftly moved through the Cardinals’ minor league system. Furthermore, he has showcased the high-octane stuff that made him a top-five pick.
Doyle, known for his “fiery competitiveness” and “swing and miss stuff,” was a standout at the University of Tennessee, where he was named the 2025 Southeastern Conference Pitcher of the Year. His college career was marked by a remarkable strikeout rate. Impressively, he shattered Tennessee’s single-season strikeout record. This dominance continued as he transitioned to professional baseball.
The 21-year-old southpaw began his professional career with a debut for the Single-A Palm Beach Cardinals. In his first outing, he recorded three strikeouts over 1 2/3 innings, signaling his ability to overpower hitters. His performance was strong enough that the organization quickly promoted him. The Cardinals assigned Doyle to the Double-A Springfield Cardinals to help with their playoff push.
In his Double-A debut, Doyle was just as effective, striking out three batters in two scoreless innings. His overall minor league stats for the 2025 season show a combined 2.45 ERA with six strikeouts in 3.2 innings pitched across both levels. While the sample size is small, his ability to generate a high number of strikeouts and hold opponents scoreless, particularly at the Double-A level, is a testament to his talent.
The lefty’s arsenal is centered around a fastball that sits in the mid-90s and has reached 100 mph. Also, he has a solid slider and cutter, which has allowed him to dominate hitters. Scouts note his ability to get the most out of his body with a high-effort, up-tempo delivery.
His rapid promotion to Double-A shows the Cardinals’ belief in his potential to be a key part of their future rotation. As the season concludes, Doyle’s impressive debut should give fans some hope for the future. Furthermore, the fireball-throwing lefty has solidified his position as one of the Cardinals’ top prospects and should be able to contribute at the big league level soon.
