Miami Marlin Agustín Ramirez boasts rare rookie power and speed. Can he refine his defense and hitting to secure his catcher job against a rising prospect?
Agustín Ramirez had some flashy numbers for the Miami Marlins in 2025.
No rookie catcher had hit more than 20 home runs and stolen more than 10 bases in a season until Ramirez accomplished that last year, so the guy clearly has talent.
But looking at Ramirez's other numbers, there's still some meat on the bone.
Ramirez is the latest subject of "Getting to Know the Fish," a Marlins Roundtable series profiling each Miami Marlins player.
Height: 6-foot-1
Weight: 210 pounds

2025: Aside from the homers and stolen bases, Ramirez's offensive numbers need improvement. His slash line ended up being .231/.413/.701, and his OPS+ was 92, eight points below the league average.
Ramirez struggled the most on defense. Ninety-one runners attempted to steal on Ramirez, and just eight of them were caught.
Although Ramirez's power numbers were enough to earn him sixth in National League Rookie of the Year voting, the Marlins would like to see improvements. The good news is, Ramirez is only 24 years old, so those improvements could come.
Outlook: Right now, Ramirez is expected to be the Marlins' Opening Day starter at catcher. But if Ramirez doesn't impress right away, he might not be in that spot long.
Miami has one of the top catcher prospects in baseball in Joe Mack.
Mack is expected to be up at some point in 2026, and exactly when that is could depend partially on how well Ramirez performs.
If Ramirez starts the year hot, the Marlins might be more inclined to keep Mack in AAA, where he can get at-bats every day. If Ramirez starts cold, the Marlins could grow impatient and call Mack up sooner rather than later.
Mack's presence puts pressure on Ramirez and vice versa, but with both capable of playing DH, manager Clayton McCullough should find room for both if they can hit. Only seven catchers hit 20 or more home runs last season, and Ramirez was one of them, so the guy has power, and other skills, such as plate discipline and contact, can come with time.
Ramirez has tools that not many catchers have, so if he can put them together, look out.
