Girardi: Latest A-Rod allegations not an issue

NEW YORK -- The Yankees are aware of the latest round of performance-enhancing-drug-related allegations surrounding Alex Rodriguez, but as far as manager Joe Girardi is concerned, it is not an issue that will affect his clubhouse.

Major League Baseball reportedly believes it has uncovered evidence that a representative for A-Rod arranged to have documents purchased from the Biogenesis anti-aging clinic that has been at the center of an investigation for allegedly supplying PEDs to a small number of well-known players, according to The New York Times.

A spokesperson for Rodriguez has "flatly denied the allegations," and Girardi said that he felt no need to address the team or seek further updates about Rodriguez's situation.

"It's an MLB issue. That's my reaction," Girardi said on Saturday. "Do I get a memo on my desk? No. I don't get a memo on my desk. I think everyone probably hears about it when you watch SportsCenter -- if you choose to watch SportsCenter -- but that's kind of the only way you kind of find out about it."

Rodriguez is continuing to rehab from arthroscopic left hip surgery performed in January and has been completing most of his exercises in New York, intending to rejoin the Yankees' big league lineup at some point after the All-Star break.

He was with the team for its Opening Week homestand against the Red Sox and briefly addressed reporters on Opening Day, but chose not to take part in on-field introductions. Rodriguez appeared in the dugout with the team on Saturday against the Orioles.

"I talked to him. I haven't seen him since last homestand," Girardi said. "He said that he's doing more and more each day. Although it was slow, he actually got on a treadmill the other day, and he was pretty fired up about that."

During the Yankees' opening homestand, players like Robinson Cano and Mariano Rivera said that it had been positive to see Rodriguez supporting the team. Girardi said on Saturday that Rodriguez's attitude seems to be fine.

"He's anxious to get back," Girardi said. "I think he wants to get on the field. That's the area that I think he knows the best and he's anxious to get on it."
