Jay Harry’s Surprising Power Jump in Upper Minors

From Draft Oversights to a Deadline Trade

Jay Harry, a six‑round signee out of Penn State in the 2023 draft, slipped past most radars after Baseball America placed him 426th among prospects. When Toronto dealt Trevor Richards to Minnesota at the 2024 deadline, the Jays received Harry, an infielder who had been labeled a “utility guy for a weak Double‑A team” by Fangraphs and ranked 87th among deadline trades. Since the move, Harry’s numbers have transformed, posting a .327/.368/.591 line between the New Hampshire and Buffalo affiliates and earning a spot among the top 40‑plus hitters in the upper minors. The trade reshaped his trajectory, turning a once‑forgotten prospect into a potential major‑league candidate.

Early Professional Struggles and Contact Evolution

Harry entered pro ball as an ultra‑contact hitter, striking out just 6.8% of the time in rookie ball but failing to produce offense. His swing‑contact rate fell from 85% in his debut season to 76% while he was in the Twins system during 2024, and dropped further to 71% after joining the Blue Jays. Power was initially scarce, with only one home run in 129 plate appearances his first year and 12 homers in 448 PA in 2024. By the next season his contact settled at 77%, while power surged dramatically. The combination of reduced contact and emerging home‑run ability signaled a pivotal shift in his development.

Swing Changes, Aggression, and New Launch Angles

Video analysis shows Harry’s swing morphing over the past three years: a very upright stance with minimal hand load in 2024 gave way to a deeper load and steeper angle in 2025, then returned to a compact, upright posture with hands out front in 2026. This season he’s been unusually aggressive, swinging at 59.5% of pitches—among the league’s highest rates and comparable to top major‑league numbers. The aggressive approach crushed his walk rate while leaving strikeout percentages unchanged. He also stopped pulling the ball as often, pulling it just 39% of the time compared with 55‑56% in the two prior seasons. Despite pulling less, his power output rose, indicating a more balanced hitting approach.

Power Metrics and the Limits of His Blast

Since moving to Buffalo, Harry’s average exit velocity sits at 90.0 mph and hard‑hit rate sits at 41%, both above‑average for his level. His maximum exit velocity, however, is 107.2 mph, which trails typical major‑league benchmarks and suggests raw power may still be developing. The lack of StatCast data from the A+ level leaves some gaps, but the on‑field numbers are hard to ignore. While he may surpass that 107.2 mph mark with more batted‑ball events, scouts’ earlier notes about limited raw power still hold some truth. His breakout appears driven more by optimizing existing tools than by a sudden burst of natural power.

Looking Ahead: Realistic Outlook for the Blue Jays Prospect

The author remains skeptical that Harry’s surge is fully sustainable, noting the absence of a clear mechanical change that explains the spike. Nevertheless, the results merit attention, especially as players near the major‑league horizon. Harry can play multiple infield spots, consistently makes contact, and when he does, shows a chance to impact games—attributes that make him a viable major‑league roster filler. He’s unlikely to become a star, but his 2025 performance opens a realistic path to the big leagues, a dramatic turnaround from just three months prior. At the very least, he should feel comfortable in any Double‑A lineup he joins.
