NEW YORK (AP) - Chicago White Sox catcher Welington Castillo was suspended for 80 games by Major League Baseball on Thursday following a positive test for a performance-enhancing substance.
The commissioner's office cited use of EPO. Erythropoietin is a hormone that stimulates the red-blood cell production and often turns up in test results for cyclists.
Castillo apologized in a statement through the players' union, saying he has "let many people down." He pointed to an "extremely poor decision that I, and I alone, made. I take full responsibility for my conduct."
