Player Summary
Brief Summary
Coupet is an undersized left-hander with elite swing-and-miss ability, highlighted by huge strikeout rates and rare spin on both his slider and curveball. Limited to three starts in 2025 due to injury, his low-90s fastball and special breaking stuff still give him a strong floor as a lefty reliever and a potential ceiling as a back-end starter heading into 2026.
More detailed breakdown
Coupet was a fun 4th round selection back in 2023 as an undersized left-hander with elite strikeout stuff. In his first full pro season, Coupet led the California League starters in strikeout percentage and was 2nd in K-BB%, showcasing both finesse and control. While Coupet only sits around 90-92, he has unteachable spin characteristics, throwing both a slider and curveball in the ballpark of 3,000 rpm, helping to generate wicked break.
Coupet went down early in 2025 after just 3 outings with High-A Spokane with an undisclosed injury, holding him out of action for the rest of the year. The hope is Coupet will be able to attack the 2026 season as his stuff is special and give him an excellent floor as a lefty pen arm and a ceiling as a 5th starter.
