Ernest Dove - My #21 Prospect: OF Eli Serrano


Outfielder Eli Serrano III lands at No. 21 on my New York Mets Top 30 Prospects countdown, bringing an intriguing mix of size, plate discipline and developing power to the organization’s farm system.

Serrano, who will be 23 for most of the 2026 season, was selected by the Mets in the fourth round of the 2024 MLB Draft during the early stages of the front office led by president of baseball operations David Stearns.

Although his early professional numbers have been modest, evaluators still see a player with a wide range of possible outcomes — from a platoon bat to a potential 20-plus home run hitter if his power fully develops.

Early pro numbers still developing, and Serrano’s professional sample size remains relatively small.

After appearing in just 17 games during his draft year in 2024, Serrano played 88 games in 2025 with the High-A affiliate Brooklyn Cyclones.  Across that stretch, the left-handed hitter posted a .222/.332/.358 slash line with a .690 OPS.

The offensive numbers don’t jump off the page, but context matters. Brooklyn’s home ballpark is widely considered pitcher-friendly, particularly for left-handed hitters due to heavy winds and spacious dimensions.

Plate discipline stands out

Despite the modest production, Serrano’s approach at the plate has drawn praise from evaluators.

Publications such as Baseball America have noted his ability to stay within the strike zone and avoid expanding at pitches outside of it. That disciplined approach gives him a foundation that could allow him to develop into an average or better hitter at the major league level.

The advanced strike-zone awareness also raises the possibility that Serrano could become a strong on-base percentage contributor as he climbs the system.

Power potential and physical tools

At roughly 6-foot-5, Serrano possesses a physically imposing frame that scouts believe could translate into significant power as he continues to mature.

Several evaluators believe the left-handed bat has the potential to develop into a 20-plus home run hitter if his power fully emerges at the upper levels of the minors.

Serrano also shows solid athleticism for his size. He has spent time in center field and has the range to handle the position, though his long-term fit could ultimately shift to a corner outfield spot where his size and power profile may play better.

Platoon questions remain

One area to monitor moving forward is Serrano’s performance against left-handed pitching.

During the 2025 season, he posted a .733 OPS against right-handed pitchers but struggled against lefties with a .569 OPS. That split raises the possibility that he could develop into a platoon bat if the issue persists.

Still, there have been encouraging flashes. Serrano has shown the ability to drive the ball the other way against left-handers, including opposite-field extra-base hits that hint at potential improvement.

2026 could be a pivotal season

Health and opportunity will be key factors for Serrano in 2026.

After playing fewer than 100 games last season, the next step is proving he can stay on the field and produce over a full minor league schedule. A promotion to Double-A would provide a clearer look at his true offensive potential.

Double-A is often considered the “prove-it” level in the minors, where prospects begin facing more advanced pitching and separating themselves from the pack.

If Serrano can translate his plate discipline and physical tools into consistent production, he could quickly rise in the Mets’ system.

For now, he remains an intriguing prospect with a wide developmental range — one whose next season could determine whether he settles in as a role player or emerges as a legitimate power threat in the organization’s outfield pipeline.
