​Luke McNeillie, a native of Milton, Georgia, attended the town’s high school that bears his name and lettered all four years, quickly establishing himself as a notable prospect on the mound. In 2023, McNeillie was regarded as one of Georgia’s top high school pitching prospects, and he had given a strong commitment to the University of Florida. He went undrafted in the 2023 MLB Draft, a development that did not deter his pursuit of advancement at the collegiate level.
In his freshman season with the Gators, McNeillie’s results did not perfectly mirror the talent evaluators’ belief in his stuff. He appeared in 26 games during the 2024 season, including two midweek starts, and posted a 7.07 ERA over 35.2 innings. He allowed 33 hits, issued 21 walks, and recorded 43 strikeouts. The following year, his sophomore campaign, saw continued variability in performance, as he logged a 4.82 ERA across 52.1 innings in 28 relief appearances and two starts, surrendering 44 hits, walking 24, and striking out 72.
That summer, McNeillie spent time in the Cape Cod Baseball League with the Harwich Mariners, showcasing his youth manpower against high-level collegiate competition. Across four starts, he recorded a 5.68 ERA, allowing eight earned runs over 12.2 innings. He yielded 12 hits, walked eight, and struck out 14 as he continued to refine his craft on a national stage.
Returning to Florida for his junior season, the then-21-year-old appeared in 18 games for head coach Kevin O’Sullivan, making three starts. He posted a 3.97 ERA in 34.0 innings, permitting 40 hits, walking 17, and compiling 48 strikeouts. Standing 6’3” and weighing 200 pounds, McNeillie possesses a slim, athletic frame and delivers from a three-quarters arm slot, exhibiting a long arm action through the back. His mechanics are straightforward and show no obvious injury red flags, though repeating his delivery remains a recurring challenge, particularly maintaining his arm angle and release point consistently.
McNeillie’s fastball sits in the mid-to-high-90s, with reports indicating a maximum velocity of up to 99 MPH. While the velocity is impressive, the pitch’s shape can be inconsistent, often displaying low spin rates for a four-seam fastball. On occasion, he has unintentionally pitched the fastball as a sinker by dropping his slot, which increases running action and would likely be more effective if he maintained a true sinking offering. He complements the fastball with a mid-80s, high-spin slider that profiles as an above-average or better pitch. With readings around 2,600 RPM, the slider features a sharp gyroscopic break, some horizontal movement, and strong downward action. McNeillie has used this pitch against both left-handed and right-handed hitters, though he also employs a changeup that has proven effective at neutralizing the platoon advantage of left-handed batters.
Statistically, over his three seasons at Florida, McNeillie has posted a cumulative groundball rate of 38.2%, a line-drive rate of 21.6%, and a flyball rate of 40.2%. He has yielded 16 home runs over 122.0 innings, translating to a manageable 1.2 home runs per nine innings. However, against professional hitters, improving the groundball-to-flyball ratio will be a critical area for him to address if he aims to thrive at higher levels of competition. As a prospect, McNeillie’s combination of velocity, breaking ball quality, and changeup feel offer tantalizing upside, with continued development in mechanical consistency and pitch sequencing likely shaping his future trajectory.
