Miami Marlins 2018 Season Review: Reliever Jesus Rosario
We don’t really have very much to go on for Jesus Rosario. The right-handed reliever just completed his second season with the DSL Marlins.
Throughout the 2018/2019 offseason, Marlin Maniac will devote one article each for every player who appeared in the Miami Marlins system for the 2018 season. Every. Single. Player. This is Part 234 of 286.
Jesus Samuel Rosario is a 6’1″, 180 lb. right-handed pitcher from Santo Domingo, Dominican Republic, population 965,040. No fewer than 177 players from the city have made it to the major leagues, including Gregory Polanco, Pablo Reyes, and Gary Sanchez.
Rosario was born on October 25th, 1999, and signed his first professional deal through free agency with the Miami Marlins on February 13th, 2017. Still just 17 at the start of his first professional season, Rosario joined the rookie-level DSL Marlins, in the Dominican Summer League four months later.

Rosario’s first professional season consisted of nine appearances, an 8.62 ERA, and a WHIP of 2.17. Opponents hit .328/.440/.403 over 84 plate appearances. Rosario allowed 12 walks and struck out 13 in 15 2/3 innings of work.
It’s important to realize that players at this stage of development generally represent the sort of low-risk, high-reward type that is unlikely to hurt the organization if they don’t pan out, but have a chance to make a huge positive future impact. Rosario is unlikely to ever advance to the major leagues, but it’s too early to say one way or the other what the future holds for him.
In 2018, Rosario remained with the DSL Marlins. On June 6th, he got into a 13-5 loss to the DSL Dodgers Robinson. Trailing 5-0, Rosario entered to pitch the fourth inning and immediately gave up a home run to Jesus Dominguez. Things didn’t get better from there. After striking out Yunior Garcia, Luis Yanel Diaz got on base on a fielding error, then took second on a pickoff attempt error. Imanol Vargas flew out, then Julio Enrique hit an RBI-single, Carlos Santiago walked, Yhostin Chirinos hit a two-run-triple, and Wladimir Chalo hit an RBI single.
10 days later, Rosario pitched in his second and final appearance of 2018 for the Marlins. He pitched a scoreless fifth inning, allowing a hit and a walk in a 4-3 victory over the DSL Red Sox1. On July 2nd, Rosario was placed on the disabled list, and remained there for the rest of the season.
