MLB suspends four minor leaguers

Major League Baseball has suspended four minor league players for drug violations.

Among the players is Luis Flores, who plays for the Chicago Cubs' Double-A affiliate in Tennessee. He received a 50-game ban after testing positive for Methylhexaneamine, a stimulant.

Minnesota Twins minor league first baseman Kennys Vargas received a 50-game suspension for testing positive for Phentermine, an appetite suppressant. Vargas is currently on the roster of the rookie league Elizabethton Twins.

Emanuel Ramirez, a minor league free agent pitcher, also was banned 50 games. He tested positive for metabolites of the anabolic steroid Stanozolol.

Pitcher Euris Quezada, on the roster of the Houston Astros' Single-A Tri-City Valley Cats, received a 25-game suspension for a violation of the minor league drug program.

All suspensions are effective immediately, while Ramirez's will start when he signs with another organization.
