The Liga Venezolana de Beisbol Profesional announced on Tuesday that Venezuelan infielder Edgar Duran will be suspended for 20 games and right-handed pitcher Guillermo Moscoso for 12 games for violating the league’s anti-doping program, which is overseen by the Players’ Association of the LVBP. 


Moscoso, 40, was born in Maracay, Venezuela, and was playing for the Tigres de Aragua, was selected to be drug tested on January 17 by the PALVBP. Duran, 33, was born in Valencia, Venezuela, and was with the Bravos de Margarita when he was selected to be tested on January 18. 

According to the league’s website, “On Feb. 6, 2024, notification of the first test was received, and on Feb. 15 of the second, analyzed by the UCLA Olympic Analytical Laboratory of the United States of America. These results came back positive for a prohibited substance.” 

The league’s website stated that it was determined to reduce Durán’s original suspension of 30 games by a third, and 20 games in the case of Moscoso, based on the program’s rules.
