The St. Louis Cardinals continued building organizational pitching depth on Day 2 of the 2026 MLB Draft, selecting left-hander Luke Harrison from the University of Texas with the 234th overall pick in the eighth round.
The 6-foot-2, 220-pound Harrison, a Houston-area product, brings a compelling blend of experience, competitiveness, and a diversified arsenal to the Cardinals’ system. At 23 years old, he is a mature, battle-tested arm who has overcome significant adversity and produced in one of the nation’s toughest conferences.
In 2026, Harrison made 19 appearances (16 starts) for the Longhorns, posting a 6-4 record with a 4.10 ERA. He struck out 100 batters in 83.1 innings while walking 35 and holding opponents to a .225 batting average. His season included a standout College World Series performance: a career-high 11 strikeouts, one earned run on two hits in 5.2 innings during a 2-0 loss to Georgia on June 16.
Just days after the draft, Harrison delivered for the USA Baseball National Collegiate Team. On Monday in Taichung City, Taiwan, he tossed five innings of two-run ball with six strikeouts to earn the win in a 10-6 victory over Chinese Taipei at the World Collegiate Baseball Championship.
Harrison’s path to the pros was far from linear. A modestly regarded recruit out of Lutheran South Academy in Houston — where he helped win three state championships — he arrived at Texas in 2021. As a freshman in 2022, the competitive lefty thrived in relief, leading the team with 32 appearances, posting a 3.06 ERA, and delivering clutch outings, including in the College World Series.
Tommy John surgery wiped out his 2023 season. He struggled in a limited 2024 return but flourished under new pitching coach Max Weiner and head coach Jim Schlossnagle’s staff. In 2025, Harrison broke into the rotation with a 5-1 record, 3.06 ERA, and 72 strikeouts in 70.2 innings. He built on that in 2026, cementing himself as a reliable weekend starter.
Over his five-year career in Austin, Harrison appeared in 79 games (33 starts), going 12-5 with three saves and a 3.83 ERA. He recorded 214 strikeouts in 200 innings. Notably, he was a teammate of recent Cardinals draftees, including 2026 fourth-rounder SS Dee Kennedy and 2025 11th-rounder INF Jalin Flores on the 2024 squad, and 2022 third-rounder LHP Pete Hansen on the 2022 pitching staff.
Harrison profiles as a polished, strike-throwing lefty with a deep pitch mix developed through hard work and coaching. His fastball, which sat in the low-to-mid 90s after velocity gains post-surgery, plays up due to his competitive demeanor and command. He complements it with a slider, curveball (often described as one of his better offerings), and cutter that helps him attack the inner half against right-handers.
Scouts value his pitchability, ability to miss bats (especially with the curve and slider), and experience against SEC lineups. While his age is a factor for some evaluators, his track record of durability, strike-throwing, and late-career breakout give him a legitimate shot to develop into a back-of-the-rotation starter or high-leverage reliever. The Cardinals, known for their player-development prowess, should find plenty to work with here.
The son of Annette Harrison and Tom Dela Garza, Harrison hails from the Friendswood area near Houston. His journey from modest high-school recruit to MLB draftee embodies perseverance and the value of program development.
For a Cardinals organization always looking to bolster its left-handed pitching pipeline, Harrison represents a smart, high-floor addition. Expect him to report to a short-season affiliate and begin his professional climb with the same bulldog mentality that defined his Texas career. Welcome to the Redbird family, Luke.
