Yankees benefiting from Cardinals' international free agency drama as top prospect shines

International free agency doesn't work like the traditional MLB Draft. Instead of a set day where names go on the board in order, teams spend months building relationships with amateur players in Latin America and often reach informal agreements, sometimes called pre-agreements, well before the actual signing period opens. Those handshake deals aren't official contracts, and until they're signed on the record with MLB, they can still fall apart — over medicals, over changed value, or, in rarer cases, over questions about a player's identity. That last scenario is exactly what reportedly happened to Yostin Peña.

Back in January 2025, Peña had a pre-agreement in place with the Cardinals worth $300,000, part of a signing class that also included bigger names like Juan Rujano ($750,000) and Miguel Hernández ($500,000), as first reported by MLB.com's Jesse Borek. But the deal never actually closed. Multiple reports at the time pointed to an MLB investigation that determined Peña's identity was indeterminate, and the agreement was voided outright. No team ever released an official statement explaining exactly what went wrong, and Peña didn't play a single game of affiliated ball in 2025 while the situation sorted itself out.

The Yankees swooped in that fall, signing Peña for $350,000 once he was clear to sign elsewhere. At the time, it barely registered outside of prospect circles — an 18-year-old outfielder with no professional track record and a strange paper trail. Less than a year later, it's looking like exactly the kind of low-cost bet that can reshape a minor league system.

Peña has been sensational in his first taste of pro ball. Baseball America's data-driven Roboscout rankings had him as the No. 8 hitter in the entire Dominican Summer League before a level-up promotion — a notable placement for a prospect signed almost as an afterthought. Over 37 DSL games, he hit .375/.457/.646 with 11 doubles, two triples, eight home runs, 24 walks, and 27 strikeouts, then jumped straight to Low-A Tampa and kept hitting, posting .310/.333/.476 with a homer in his first 10 games there.

Baseball America's report also flagged the underlying data: a 107.9 mph 90th-percentile exit velocity in the DSL, a 47.1% hard-hit rate, and a max exit velo of 115.1 mph, translating to at least 70-grade raw power on the 20-80 scouting scale. His approach is aggressive — a 48.7% swing rate and a 31.2% chase rate — but the report notes his damage numbers justify the aggression, with the open question being how much his hit tool gets exposed against tougher pitching at higher levels. He started in the DSL All-Star Game and, in late July, he signed with agent Scott Boras — the kind of rare representation that's due for a remarkable teenager.

The scouting buzz backs up the numbers. FanGraphs' Eric Longenhagen broke down Peña's game in a recent prospect chat, noting a swing that's far more controlled than his 6-foot-4, 205-pound frame would suggest, staying back on breaking balls while still doing damage on pitches he can pull. He drew a stylistic comparison to the hitting hands of Dodgers infield prospect Emil Morales, praised Peña's plus speed in center field, and some fan comments floated a loose "young Aaron Judge" framing for his sheer physical projection: size, tools, and ceiling, not performance history.

Peña isn't on an official Top 30 list yet, and given his age and the level he's playing at, a big-league debut is still years away. But between the Roboscout placement, the underlying exit-velocity data, and the fact that he's 18 and now playing in the states, still dominating — it wouldn't be a surprise if his name starts climbing organizational and industry rankings once the full slate of end-of-season scouting reports comes out. A player this toolsy, performing this well, for $350,000, is exactly the kind of story that makes the international market so unpredictable. St. Louis passed. But the Yanks saw an opportunity, didn't hesitate, and right now, it's paying off in a big way.
