Miami Marlins minor league pitcher Eiver Mosquera has received an 80-game suspension for testing positive for Boldenone, a performance-enhancing substance.
This season with Class-A Jupiter and the rookie-level Florida Complex League Marlins in 12 games (nine starts), the 19-year-old was 3-3 with a 4.50 ERA, 30 strikeouts and 16 walks in 38 innings.
Mosquera joined the organization in 2024 as a $150,000 international signing out of Venezuela.
