Mets Make Announcement on Disappointing 23-Year-Old Outfielder

The New York Mets quietly announced they added a familiar name back onto Binghamton’s active roster Tuesday, hours before they hosted the best team in baseball.

Eli Serrano III, still listed among the organization’s top 25 prospects and ranked as high as No. 15 by MLB Pipeline, came off the 60-day injured list and immediately reminded people why the club has kept pushing him.

In his first at-bat with the Rumble Ponies after more than two months away, the 6-foot-5 left-handed hitter drove a solo homer to left field, his fourth of the season.

That swing was the highlight of an otherwise thin 2026. Serrano has slashed just .188 with a .643 OPS across 62 games and 218 at-bats between Double-A and a short rehab stint in St. Lucie. Four home runs and 22 RBI is modest production for a player whose entire prospect case rests on raw power and a patient approach.

The numbers look even thinner once you account for the calendar.

Binghamton first put him on the seven-day injured list in mid-June; the club later moved him to the 60-day list in early August. Reports earlier in the year noted he had been playing through a shoulder problem. An ankle issue had already cut into his 2025 season at High-A Brooklyn. Development time keeps disappearing.

The Mets drafted Serrano in the fourth round in 2024 out of NC State after he went undrafted from high school. They paid him a slightly above-slot bonus and have advanced him to Double-A despite the recurring absences.

Evaluators still see a future corner outfielder with above-average arm strength and the frame to grow into more power. The timetable has always pointed toward 2027 or 2028, and a late-season homer will not change that projection by itself.

What it does is give the organization one more look at whether the tools can survive a full, healthy stretch.

For now the picture remains incomplete. A slugging prospect who has spent large portions of two straight summers on the injured list and is hitting under .200 at Double-A has not delivered the kind of year his ranking suggested.

The first-at-bat homer was a welcome sight. It does not erase how disappointing the rest of the season has been. Binghamton can use the left-handed bat down the stretch.

The Mets still need to see whether Serrano can stay on the field long enough to prove the power is more than occasional.
