Marlins Rotation Prospects 2024: RHP Delvis Alegre

Minor league pitcher Delvis Alegre is still likely four full seasons away from the Miami Marlins.

The Miami Marlins minor league system runs seven layers deeper than just parent club talent. Delvis Alegre, who turns 19-years-old today, has spent most of the past two seasons with the Rookie-level DSL Marlins in the Dominican Summer League.

Right-hander Alegre was initially signed by the Marlins on July 2nd, 2017 while still just 16-years-old, and didn’t make his first professional appearance with the DSL Marlins until the 2018 campaign. He was 1-2 with a 3.06 ERA in 14 games, including five starts. He struck out 36 batters in 47 innings, walking 15 and finishing with a WHIP of 1.383.

Not rock star stuff, to be sure, but at 17, worth another season at least. Alegre came through with flying colors for his sophomore effort in DSL. He went 3-4 with a 2.58 ERA and dropped his WHIP all the way down to 1.063 in a team-high 58 1/3 innings. He struck out 40 and walked 17 with the team before earning his first promotion late in the season.

On August 25th, just five months ago, Alegre was promoted to the GCL Marlins, in the Rookie-level Gulf Coast League based out of Jupiter, FL. Limited to only one inning at the new level, he struck out a batter in a perfect sixth inning of a 7-3 Marlins win over the GCL Cardinals on August 27th.

Fangraphs didn’t have much to say about Alegre, but gave him a brief two-sentences in an article about Miami’s top prospects. When referred to as part of a group of “projectable” pitchers including Eury Perez, Mario Doble, and Maycold Leon:

"Alegre, 18, is the most polished of the bunch and arguably the most athletic. He has a four-pitch mix and is up to 95."

Alegre remains with the stateside rookie affiliate, where he’ll likely reside through this calendar year barring a start that necessitates another quick promotion. The next level up for Alegre is the Short-season-A Batavia Muckdogs in the New York-Penn League. Like the DSL and the GCL, the NYPL also begins their season in late-June/early-July, and won’t really throw a wrench into Alegre’s development to higher levels.

Alegre’s eventual progress through the minor leagues, if he continues to make the cut, should be to Batavia late this year and to the Single-A Midwest League’s Clinton Lumberkings sometime in 2021. Logical next steps would see him make stops with the High-A Jupiter Hammerheads in the the Florida State League in 2022 and with the Jacksonville Jumbo Shrimp in the Double-A Southern League in 2023. 2024 would see him likely with the Triple-A Wichita Wind Surge in the Pacific Coast League with a chance at denting the major league roster at some point that year.
