TORONTO — A sports doctor at the center of drug investigations in Canada and the United States said Monday he treated Alex Rodriguez after the Yankees slugger had hip surgery last year and prescribed anti-inflammatories but not human growth hormone.

Dr Anthony Galea also told The Associated Press an assistant who was stopped at the US-Canadian border in Buffalo, NY, last year was carrying only a minuscule amount of HGH — which Galea said was for his own use. The doctor reiterated he has never given the drug to an athlete.

"I only brought enough for her to do two injections into me because I was away for two nights," said Galea, who believes authorities and the media have exaggerated the accusations involving him and his practise.

"They made it look like I had 100 vials. I had one little vial and two doses were for me and you think that someone along the line would ask "'Well how much is there?'"

Rodriguez and other high-profile baseball players including Jose Reyes and Carlos Beltran have been contacted by US federal investigators regarding Galea. Reyes and Beltran each say they did not receive HGH from Galea.

Rodriguez said last week he was "aware" of the investigation and plans to cooperate with the government. He declined to comment again when asked about Galea after he left New York's spring training game on Monday against the Pittsburgh Pirates.

Galea said he helped with Rodriguez's rehabilitation from hip surgery last March.

"He had a damaged hip. Inflamed. It was damaged," Galea said in an interview at his clinic. "He needed anti-inflammatories for his hip. I was basically helping in the rehab."

The Yankees released a statement last Monday saying they never authorized Galea to treat the slugger. If Rodriguez was treated without club consent, any attempt to determine whether he violated his record $275 million, 10-year contract, its guarantee language or baseball's collective bargaining agreement likely would hinge on whether treatment was elective or necessary.

A message was left on Monday seeking comment from Dr Marc Philippon, who performed Rodriguez's hip surgery.
