Two minor league pitchers, Luis Custodio and Luis Sierra, received 56-game suspensions on Monday after testing positive for banned substances as part of the minor league drug program. The suspensions result from positive tests for Stanozolol, a performance-enhancing drug.
Details of the Suspensions
The announcement from the commissioner’s office confirmed that both players tested positive while participating in leagues outside the United States and Canada. Custodio, a 21-year-old left-handed pitcher, had a mixed performance last season with the San Francisco Giants Black team in the Dominican Summer League. He recorded a 2-1 win-loss record alongside a 7.94 earned run average (ERA) in 12 relief appearances after recovering from Tommy John surgery. Custodio signed with the Giants in 2023.
On the other hand, Sierra, a 20-year-old right-hander, was a recent addition to the league, having signed with the Baltimore Orioles for a $10,000 bonus in June 2024. He struggled in his debut season, finishing with an 0-2 record and a 9.95 ERA over 11 relief appearances. Sierra was officially released on January 5, 2025, and his suspension will take effect once he signs with another major league organization.
Context of Drug Testing in Minor League Baseball
This marks a significant moment in the ongoing efforts to maintain integrity within baseball. This year alone, three players have faced suspensions due to positive drug tests. Notably, free agent outfielder Max Kepler received an 80-game suspension last Friday under the major league program for testing positive for Epitrenbolone.
The enforcement of drug policies aims to ensure fair competition and protect the health of athletes. Both Custodio and Sierra now face a substantial setback in their careers, which will require them to navigate the implications of these suspensions.
As the season progresses, the focus remains on the players’ responses and how they will work to regain their standing in professional baseball.
