Nationals Prospect Sime Jr. Dominates with New Slider in 2026
Miguel Sime Jr. added a deceptive slider to his triple-digit fastball, posting elite strikeout numbers across two levels in his first full pro season.
Washington Nationals pitching prospect Miguel Sime Jr. had a breakout 2026 minor league season after developing a new slider grip during spring training. He posted a 41.3% strikeout rate overall and a 14.87 K/9 after a mid-season promotion to High-A. The Nationals aggressively challenged him by moving him up from Low-A, signaling organizational confidence in his development. His profile now draws comparisons to Jarlin Susana given his velocity, pitch mix, and swing-and-miss ability.
