Argenis Cayama

Organization Prospect Rankings

• 
  Ranked San Francisco Giants #30 prospect in 2025
  BA Grade/Risk: 45/Extreme.
  
  Track Record: Early in his amateur career, Cayama was an outfielder who wasn’t garnering much interest from professional clubs. Once he converted to the mound and started showing a low-90s fastball, things changed. He signed for $147,500 and was one of the more interesting prospects among the Giants’ two clubs in the Dominican Summer League. He dealt with a bout of pneumonia early in the season and had to work to regain his strength.
  
  Scouting Report: From an athletic delivery, Cayama starts his mix with a low-90s sinking fastball with excellent armside run that peaked at 96 mph. He backs it with a low-80s gyro slider and a mid-80s changeup. The slider is a short-breaker with decent spin and the changeup shows late dive despite being thrown sparingly compared to his other two pitches. He has a confident mound demeanor, and scouts were heartened by his athleticism and the room for projection on his body. Cayama did a solid job pounding the strike zone and his background as a position player should help him repeat his delivery even if his body changes as he matures.
  
  The Future: Cayama will move stateside in 2025 and is one of the Giants’ more up-arrow pitching prospects. He has the upside of a No. 5 starter and the fallback option of a fire-breathing reliever who can dominate the late innings.
  
  Scouting Grades: Fastball: 60 | Slider: 50 | Changeup: 40 | Control: 55.
