The New York Mets might be navigating a turbulent season, but they just uncovered a potential diamond in the rough. Rookie outfield prospect AJ Ewing made a thunderous MLB debut on May 12, and fantasy baseball managers everywhere are taking notice.
In his first game, Ewing went 1-for-2 with a triple and drew three walks, posting a jaw-dropping 1.500 OPS. Yes, it's a tiny sample size, but the underlying numbers suggest this is no fluke. The Mets didn't rush his call-up; Ewing earned it by dominating the minors. He hit .349 in Double-A Binghamton and .326 in Triple-A Syracuse this season. With Luis Robert Jr. sidelined indefinitely due to a lumbar disc herniation, the Mets need Ewing to patrol center field—and he's ready for the spotlight.
At just 21 years old, Ewing is the organization's No. 2 prospect. Drafted in the fourth round out of Springboro High School in Ohio in 2023, he's built for the modern game. Scouts rave about his ability to hit any pitch to all fields, and he's cut his strikeout rate by nearly 10 percentage points this year. But his most electric tool? Elite speed. Ewing is a "plus-plus runner" who stole a staggering 70 bases across 124 minor-league games in 2025. That speed translates to both the basepaths and the outfield grass, where he covers serious ground.
While Ewing isn't a power hitter, his .315 minor-league batting average and elite plate discipline make him a contact machine. Those three walks in his debut? They signal a hitter who knows the strike zone. For fantasy managers, this is the kind of profile that wins leagues: high batting average, stolen bases, and runs scored.
The verdict is clear: AJ Ewing is a must-add. After his debut, his fantasy ownership jumped from near-zero to 11%, but that number will climb fast. The Mets' outfield depth chart is thin behind him—Jared Young is more of a utility infielder—so Ewing has a clear path to everyday at-bats. If Robert's back issue lingers, Ewing could be a season-long difference-maker.
Don't overthink this one. Head to your waiver wire and make the bid. Players with this blend of speed, contact, and opportunity don't come around often—and they can turn a fantasy season around.
