Jack Leiter

Leiter was a first-round talent out of high school and ranked as the No. 21 prospect in the 2019 class, but a high price tag and strong Vanderbilt commitment meant he got to campus in Nashville. Draft-eligible in his second year with the Commodores, Leiter—the son of long-time big league pitcher Al Leiter—dominated in his first full season of collegiate baseball, posting a 2.12 ERA over 76.1 innings and 13 starts, while striking out 127 batters (15 K/9) and walking 34 (4.0). Known for his polish and pitchability out of high school, scouts continue to praise Leiter’s moxie on the mound, with a deep pitch mix that includes five offerings if you count a two-seam and four-seam fastball. Leiter is a shorter righthander, listed at 6-foot-1, 205 pounds, but he has added strength to his frame since high school, particularly in his lower half. This spring, Leiter has primarily worked with a fastball, curveball, slider combination. His fastball has been up to 98 mph, but averages 93-95 mph, with excellent carry that generates plenty of whiffs in the zone and above it. Teams love the metrics on Leiter’s fastball, and the combination of his size, extension and carry on the pitch allow it to play up, even when he’s sitting in the 90-93 mph range. His curveball is his best secondary offering now, an upper-70s, 12-to-6 downer that he lands consistently in the zone when he wants but can also bury for a put-away pitch. Leiter throws a slider in the low 80s that has less depth but might wind up being a better out-of-the-zone chase offering and he also infrequently throws a mid-80s changeup that scouts loved out of high school and could become an above-average secondary with more reps. Durability was the one concern scouts had with Leiter, and while he did post most weeks throughout the season, he skipped one start to manage fatigue and at times was a bit homer-prone. While Leiter might not project as an ace, scouts see a pitcher who should fit in a No. 2 or No. 3 role and pitch in the big leagues for a long time.
