MACK - Let's Get To Know - IF - Branny De Oleo

 


The New York Mets promoted IF Branny De Oleo from A-St. Lucie to AA-Binghamton


Branny Steven De Oleo
is a 21-year-old shortstop (and utility infielder) in the New York Mets’ minor-league system.

Basic Info
  • Born: May 15, 2005, in Santo Domingo, Dominican Republic
  • Listed Height/Weight: 6'1", 156 lbs
  • Bats/Throws: Right/Right
  • Position: Primarily SS; also played 2B and 3B (and some outfield in 2026)
  • The Mets signed him as an international free agent (undrafted free agent) on January 15, 2023, to a minor-league contract. He was a relatively low-bonus/older signing in that class. He made an immediate impact in his pro debut. 
  • In 2023 with the DSL Mets Blue (Dominican Summer League, Rookie level), he hit .313/.403/.476 with 3 HR, 25 RBI, and 6 SB in 46 games. He showed strong contact skills (only ~9% strikeout rate), athleticism, and projection for added power. Scouts noted his range, arm, and instincts at shortstop. Baseball America called him a “sleeper prospect” and one of the Mets’ more pleasant developmental stories that year; he ranked as high as the Mets’ No. 24 prospect in some 2024 rankings.
Performance Since ThenHe struggled after moving to the U.S. stateside complexes:

  • 2024 (FCL Mets, Rookie): .209/.284/.302, 2 HR, 14 RBI, 4 SB, 42 games.

  • 2025 (FCL Mets, Rookie): .194/.291/.290, 1 HR, 13 RBI, 16 SB, 44 games.

In 2026 (first full season at Single-A with St. Lucie), through about 80 games he posted .229/.309/.353 with 7 HR, 40 RBI, and 10 SB (302 PA). His strikeout rate rose notably (~27.5%), though he showed some power and speed. He had a solid stretch in May (.292/.346/.500 in one report) and hit a go-ahead two-run homer in a May 2026 win over Palm Beach. Overall career minor-league line: roughly .239 AVG, 13 HR, 36 SB in ~695 AB. OutlookDe Oleo is a developmental project with tools (athleticism, defensive potential at short, room to add strength/power). Contact and consistency have been issues at higher levels so far, and he is not currently viewed as a top prospect in the Mets system. He remains a long-shot organizational player who could develop further if he refines his approach and adds physical strength.

I always try to look at guys based on potential to get to the big leagues. Objectively, many Mets prospect infielders stand between Branny and the majors. So, if I was Branny., listed at 6’1” 156, what would I do? Get to 6’1” 185 by spring training, and see if added strength could change the calculus. Because the odds are super long, unless he changes something.

Agreed (again)

A friend of mine is a heavy equipment operator who frequently hit the gym and was a muscular 6 foot three, 320 pound behemoth. He decided to completely change his diet while still continuing at the gym, and he is now a 6 foot three 220 pound sculpted specimen. He is in his early 50s. He just decided to do it for health reasons. It shows how receptive to adjustment the body is with enough concerted effort and focus. All of these guys that are on the margin, with very long odds, staring them in the face, I would look at what I could change to push myself up the list. The answer for a lot of them would be to go crazy in the weight room this off-season.

I just read this, which makes me a little hesitant to recommend the weight round to put on weight for a guy who may have already put on Weight, but his current weight is not listed on his that page. “Jefferson Rojas is listed at 5-foot-11 and 150 pounds on public sites, but Mets people tell me…that he is a little taller than that and his weight is up to 200 pounds. That growth has led to an uptick in power in 2026, with him slashing .270/.339/.461 with 19 doubles and 15 home runs in 91 games prior to the trade. “ Mauricio was another example, listed at 166 for years. Obviously 40-50 pound too low.
