Yordin Chalas

Organization Prospect Rankings

• 
  Ranked Arizona Diamondbacks #20 prospect in 2025
  BA Grade/Risk: 45/High.
  
  Track Record: Chalas was already touching 94 mph when he signed for $10,000 at 18 years old in 2023, but possessed little else in the way of refinement or secondary offerings. He has since emerged as one of the more intriguing arms in the system, in no small part because his fastball now sits in the upper 90s. He struck out 72 batters to just 26 walks over 50.2 innings of relief between both Class A levels in 2024.
  
  Scouting Report: Chalas’ 97 mph fastball now touches triple digits. It’s a lively albeit inconsistent offering; sometimes it sinks, sometimes it carries, neither necessarily by design. His mid-80s slider is short and darting against lefties, but bigger and sweepier to righthanded batters. He worked on adding a changeup after the season, settling on a splinker that team officials say flashed plus. So far, Chalas has only pitched in relief. But his strike-throwing, athleticism, relatively controlled delivery and easy velocity has led the organization to consider giving him a chance to earn starter looks—and at the very least multi-inning relief reps—in spring training.
  
  The Future: Most see Chalas as a future late-inning bullpen arm, but the D-backs will at least explore the possibility of him becoming something more when camp opens in 2025.
  
  Scouting Grades: Fastball: 65 | Slider: 50 | Changeup: 45 | Control: 45.
