28. Konner Eaton (75 points, 12 ballots)
Eaton, a 23-year-old lefty pitcher, was a bit below the radar entering 2025, but his size and athleticism were intriguing. He throws in the lower half of the 90s and boasts a slider whose late horizontal movement is effective against hitters from both sides of the plate. Eaton has a sturdy, durable frame (6’3”, 210 pounds) that projects well as a traditional starting pitcher. His delivery is athletic, though he has worked on simplifying his mechanics since turning professional to improve his overall strike-throwing ability.

Eaton, who signed for a full-slot bonus of $378.9k after getting drafted in the sixth round in 2024, threw 62 innings across 14 starts in his platform draft year, though his results (5.66 ERA, 1.58 WHIP, 4.9 BB/9 rate, 11.9 K/9 rate) weren’t strong and the level of competition wasn’t notably high. Unusually for a newly-drafted pitcher, Eaton actually saw some action in affiliated ball as well, throwing 11 innings across nine relief appearances in Low-A Fresno and High-A Spokane, allowing just one run on six hits and three walks while striking out 16.
In 2025, Eaton was assigned back to High-A Spokane, where he was 1.2 years younger than league average. Eaton was a rotation stalwart for Spokane, starting 23 games and throwing 121 1/3 innings with a 3.56 ERA, 1.25 WHIP, 9.3 K/9 rate, and 3.1 BB/9 rate while holding lefties to a .603 OPS. That includes quality starts in seven of eight starts between mid-June and early August. In mid-August, Eaton was promoted to Double-A Hartford, where he was 2.7 years younger than league average. He took the mound for another four starts in the Eastern League, throwing 18 2/3 innings with a nice 11.6 K/9 rate, albeit a 5.30 ERA, 1.34 WHIP, and 4.8 BB/9 rate.
Here’s a look at Eaton’s 2025 highlights:
Eaton was ranked 180th overall in the 2024 draft rankings by MLB Pipeline and is currently ranked 21st in the system as a 40 FV prospect with a 55 grade on his slider and 50s on the fastball and changeup:
At 6-foot-3, Eaton’s combination of size and athleticism have long intrigued scouts. While he typically runs his fastball up to about 94 mph, it can miss bats with solid inverted vertical break. His low-80s sweeping slider is an above-average breaking ball that can serve as an out pitch at times, and while his changeup has been inconsistent in the past, it’s a third effective offering for the southpaw.
After walking 5.0 per nine innings over the course of his George Mason career, there were questions about Eaton’s ability to start long term. He was finding the zone much more consistently at the outset of his pro career, and if that continues along with his three-pitch mix, he does have the chance to stick in a rotation. If not, the fastball-slider combination could play up coming out of the ‘pen in shorter stints.
Eaton’s “vertical” attack plan (high fastballs and sweepy sliders) is a good fit for Coors Field if he can locate well, as high-spin sliders are less affected by the thin air than traditional curveballs. Eaton’s total 140 frames in 2025 represents a clear starter’s workload in this day and age, setting him up to be an innings eater option in the upper minors or even MLB.
Eaton should head back to Hartford to begin the year, so a reasonable trajectory might be to see him in purple pinstripes by the end of 2027. He might yet be sent to the bullpen if his command falters against upper minors hitting, but the current starting role and results make him a 35+ FV player in my book, one who just missed inclusion on my ballot.
