The number of drug tests conducted by Major League Baseball rose three percent in the past year. This season, Rockies catcher Eliezer Alfonzo was the only big leaguer suspended for using a performance-enhancing substance. Alfonzo was banned for 100 games and there was just one positive for PEDs among 3,868 tests that resulted in discipline, according to the annual report issued Thursday by Dr. Bryan Smith, the independent administrator for baseball's drug program.
