Coby Mayo has struggled to find his footing in the major leagues since he made his debut in 2024. He's a career .209 hitter with a .683 OPS in 211 games across his three seasons. The Baltimore Orioles haven't done him many favors either, though.
Mayo was a top-30 prospect in the game coming up as a corner infielder, and the Orioles never cleared a pathway for him to regular playing time. Baltimore has constantly had everyday players at first, third, and DH, making Mayo a bench/rotation player; not an easy situation for a young player to continue to develop.

Mayo has looked better in 2026, though, finding his power stroke and finally carving himself a role. The righty has been one of the best hitters against left-handed pitchers in baseball this season. Among the over 200 hitters with more than 100 plate appearances against lefties, Mayo's 1.148 OPS is the highest. He leads all players in home runs (15), WRC+ (218), and his 32 RBIs are 5th.
Coby Mayo is finally showing off some of what his prospect pedigree predicted
Coming through the minors, Mayo was projected to be a middle of the order bat. In 2025, MLB Pipeline wrote, "He’s also become a better all-around hitter who takes walks and can drive the ball to all fields, even if most of his over-the-fence pop comes on his pull side." Baltimore has been hoping for that hitter since his debut, but he hasn't matured to that level, at least against righties.
Carving himself a role against lefties is a big step in his development. He is really showing off his raw power, with an over 50% hard-hit rate, up there with Junior Caminero, Jordan Walker, and Oneil Cruz. His 33.3% home-run-to-fly-ball ratio is tops among all hitters too. It's not just the power either; he has a .325 batting average. The only part of his game not to reach its potential has been the on-base ability.
Mayo has been a godsend for the Orioles against southpaws this season. As a team, without Mayo, the O's are hitting .231 with a .681 OPS and a 93 WRC+. With Mayo, it's a .720 OPS and 103 WRC+.
Sometimes a prospect needs to find his niche to make an impact before the rest of their game can develop. With other young players on the roster needing at-bats at Mayo's primary positions, the O's were never able to get him the necessary, regular playing time to reach his potential. Now, he's showing Baltimore can't take him out of the lineup against lefties, and that is the start to the regular playing time he can use to develop the rest of his game and reach the top prospect potential he showed in the minors.
