Padres promote 20-year-old Ethan Salas as September roster expands — youngest MLB catcher since 1991; what his

Padres officials have described Salas as a "third-catcher" type for now: a player who will catch occasionally, pinch-hit against lefties and serve as a DH option in righty-heavy matchups. That aligns with how clubs usually use top prospects in September: protect them from everyday exposure while leveraging their strengths where they help most.

MLB coverage notes Salas' strong recent numbers in Double-A and Triple-A and his defensive reputation; national outlets emphasize that he would be the youngest big-league catcher since Ivan Rodriguez in 1991 — a historical footnote that underscores both the rarity of the move and the club's confidence in his readiness.

San Diego is pushing through a tight National League wild-card scramble with fewer than 25 games left on the calendar. Adding Salas gives the Padres a low-risk, high-upside option to tweak late-inning matchups, rest starters and protect the club against further injuries.

Rather than pursuing a short-term veteran rental, the promotion signals a preference for internal depth and controllable talent that could carry into October — an approach that can save payroll flexibility while changing how manager decisions play out in close games.

The biggest unknowns are how often Salas will play, whether he will make the postseason roster, and how his recent recovery from a 2025 back injury will hold up under big-league workload. The Padres have been cautious so far; Stammen declined to use Salas in a tight game immediately upon his arrival.

What is clear: Salas' call-up is more than a feel-good story. Its a tactical addition with immediate implications for San Diegos bench construction and late-game deployment during a crucial stretch of the season.
