Background
Mejía was born on August 26, 1996, in Gaspar Hernández, Dominican Republic. He broke into the majors at 24 years old, making his MLB debut with the Cleveland Indians in 2021. A right-hander in every sense, he has worked primarily as a reliever throughout his time in the United States.
Professional Career
Mejía’s big-league debut was a tough one. In 2021 with Cleveland, he posted a 1-7 record and an 8.25 ERA over 52.1 innings — but he did punch out 47 batters, showing he could handle a workload at the highest level. The raw stuff was there; the results just weren’t.
He moved on to the Milwaukee Brewers for 2022 and 2023. The 2022 stint was brief and rough — just 2.1 innings with a 23.14 ERA. But 2023 showed real progress: a 5.56 ERA with 13 strikeouts in 11.1 innings, a modest step forward for a pitcher still searching for consistency at the MLB level.

Winter Ball: Where Mejía Became Elite
The LIDOM chapter is where this story gets interesting. With the Tigres del Licey, Mejía has transformed into one of the most dependable closers in Dominican winter ball — and the numbers back it up completely.
He posted a 2.76 ERA in 16.1 innings during 2023-24, then tightened things up to a 1.88 ERA with 13 saves in 24.0 innings the following winter. In 2025-26, he was nearly untouchable: 1.01 ERA, 8 saves, and 27 strikeouts in 26.2 innings. And in the current 2026-27 season, he’s been perfect — 0.00 ERA in 4.0 innings with 2 saves.

The Bigger Picture
Mejía’s career draws a sharp contrast between two worlds. In MLB, he’s been a work in progress — a big arm fighting for footing at the top level. In the Dominican Republic, he’s a closer who gets outs when it matters most. That gap isn’t a contradiction; it’s a reminder that baseball development doesn’t follow a straight line, and that some pitchers find their groove competing at home, where comfort and confidence can make all the difference.
If you want to understand how a pitcher with MLB experience can completely reinvent himself as a shutdown closer, Mejía’s LIDOM run is required viewing.
