St. Louis Cardinals minor-league pitcher Leonardo Taveras has been hit with an 80-game suspension following a positive test for the performance-enhancing substance Clomiphene.

That substance is seen as a masking agent. It is regularly an estrogen modulator and would not offer any kind of benefit to a baseball player.

The 80-game suspension is the direct result of baseball’s minor league drug program. Eight players have been suspended under the minor league program so far this season.

Taveras had a 1-1 record with 2 saves in 20.1 innings of work this season with Peoria, the Cardinals’ high-A franchise. The 6-5, 190-pound pitcher is a considered a hard thrower, and he had 38 strikeouts to this point in the season.

Taveras is considered the No. 18 prospect in the Cardinals system by FanGraphs. While Taveras has a bit of age on him as a 24-year-old prospect, FanGraphs estimates that he will make it to the big leagues by the 2025 season.
