Miami Marlins Prospect Watch: Spotlight on Dalvy Rosario
It’s important to understand that the Dominican Summer League is the most junior of professional baseball leagues, comprised of players between the ages of 16 and 20.
Undrafted free agents, traditionally from Latin countries, start their professional careers here. Jarlin Garcia (2011), Jose Urena (2009), and Marcell Ozuna (2008) are amongst the recent Miami Marlins graduates of the DSL. Miguel Cabrera was a product of the system as well, and we all know that he’s going to the Hall of Fame in a few years.
Dalvy Rosario is a 6′, 160 lb. shortstop who plays with the DSL Marlins. Rosario will be turning 18-years-old on July 22nd. In 30 games with them, he has slashed .286/.317/.446, with a .763 OPS. That OPS ranks him second on the team behind Alvaro Montero, and first with his slugging percentage. His four home runs rank top on the team as well.
Rosario is on a five-game hitting streak, during which he’s gone nine-for-18 with seven RBI. During that time, he has raised his average from .245 to .286, and it seems to be still climbing. Last night, he was three-for-four with a home run and three RBI.
Defensively, Rosario has played second base, third base, and center field in addition to shortstop. In fact, shortstop is his least manned position, despite his designation. Dalvy has made two errors in just 28 innings at shortstop, in 12 chances for an .833 fielding percentage. He’s also made an error in 34 chances playing 78 innings at the hot corner.

Conversely, Rosario is fielding 1.000 at both second base and in center field, in 32 and 25 chances, respectively. The DSL Marlins coaching staff, led by manager Raymond Nunez, have used Rosario mostly between third and fifth in the batting order.
Rosario was not mentioned when the Miami Marlins signed their most recent crop of international free agents, including Ynmanol Marinez, Julio Machado, Jonathan Chinchilla, Jean Carlos Flores, Zaquil Puente, Jhonaiker Osor, Adonis Giron, Elvis Osoria, Anthony Felipe, Jandel Paulino, Delvis Alegre, Yeuris Jimenez, and Josan Mendez.
We’ll keep our eyes trained on the south and hope for Rosario’s success going forward. The previously unheralded infielder is only getting better, standing out with and against other, more heralded signings.
