VIERA, Fla. -- Washington Nationals pitcher Gio Gonzalez says tests for performance-enhancing drugs he was given by Major League Baseball have come back negative.
Gonzalez and other players were reported in the Miami New Times as being listed on records of a now-closed anti-aging clinic that purportedly supplied performance-enhancing drugs to athletes.
In a brief statement, Gonzalez said Friday that the players' association informed him that blood and urine tests he was given two days after last month's report came back clean.
He said he expected the negative results and reiterated that he has never taken any performance-enhancing drugs.
The Nationals' left-hander didn't take any questions beyond his statement, citing MLB's ongoing investigation into Biogenesis of America LLC.
ESPN's "Outside The Lines" reported Tuesday that two sources, speaking independently, identified Gonzalez as the only Anthony Bosch client named thus far who did not receive performance-enhancing drugs. A document obtained by "Outside the Lines" bolsters their case: On a computer printout of clients, Gonzalez, identified by the code name "Gladiator," is said to have received $1,000 worth of substances, but under "notes" are several substances not banned by Major League Baseball: "gluthetyn" (which a source said was a misspelling of glutathione), "IM [intramuscular] shots" and amino acids.
Glutathione is an anti-oxidant, and one source said the "IM shots" Gonzalez received were "MICs," a medically dubious but legal combination of methionine, inositol and choline, often used for weight loss.
At least 25 players, either by name or nickname, are identified in the Biogenesis documents. Sources have indicated the number of MLB players who dealt with Bosch over the years could be significantly higher.
