Chicago White Sox catcher Welington Castillo has been suspended 80 games for violating the league's joint drug agreement, Major League Baseball announced Thursday.
Castillo is being banned for using erythropoietin (EPO), a performance-enhancing substance.
Castillo, a 31-year-old from the Dominican Republic, is hitting .270 with six home runs and 15 RBIs for the White Sox this season. He was behind the plate for Wednesday's 11-1 win over the Orioles, going 1-for-5 at the plate.
It's the second notable MLB drug violation this month. Seattle Mariners second baseman Robinson Cano received an 80-game ban after testing positive for Furosemide, a diuretic that is not a performance-enhancing drug but is viewed as a masking agent and is on MLB's banned substance list.
