New York Yankees slugger Jason Giambi is putting baseball's steroid probe behind him and focusing on healing his injured left foot. 

Giambi, shelved since May 31, told reporters Monday that he couldn't talk about last Friday's meeting with former U.S. Senate majority leader George Mitchell, who is overseeing baseball's investigation into steroids.

Giambi was the first active major leaguer to be interviewed by with Mitchell, who has handled the probe since March 30, 2006.

"I have been asked not to comment about it," Giambi said. "Sorry about that."

"My biggest thing is, I'm more concerned about getting back going and, hopefully, get a chance to … start rehabbing and get back to playing baseball. Not worrying about anything else."

Giambi, 36, agreed to meet with Mitchell when commissioner Bud Selig threatened to suspend him if he refused to do so.

Giambi was asked to co-operate with the steroid probe after he was quoted in USA Today as saying: "I was wrong for doing that stuff. What we should've done a long time ago was stand up — players, ownership, everybody — and said: 'We made a mistake.'"

Giambi's comment was interpreted as an admission of steroid use, and he was summoned to the commissioner's office by Selig on May 23 and told to meet with Mitchell.

Giambi shelved with foot injury
 
Giambi is hitting .262 with seven home runs, 23 runs batted in and 19 runs scored in 45 games this season, his sixth with New York.

But he began struggling when shifted from designated hitter to first base, averaging .117 with three HRs and six RBIs in May.

Giambi realized something was seriously wrong when he homered in the seventh inning of a 3-2 loss to the Toronto Blue Jays on May 29.

He originally was diagnosed with a bone spur, and switched to cleats with an orthotic device that helped relieve the pain temporarily.

Giambi later learned that he suffered torn tissue in the arch of his left foot, and was fitted with a walking boot and put on the disabled list.

Last week, he received medical clearance to resume working out at the Yankees' spring-training complex in Tampa, Fla., and is hoping to return to the lineup in a few weeks.

"I'm excited to be doing something," he said. "Getting the opportunity to come out here, get working and finally do something instead of sitting around.

"The biggest thing is try not to go fast," he said. "But I want to go fast enough where I can, hopefully, come back, and make a difference.

"I'm at that point where I need to do more to find out what I could do and could not do. I'm going to push more and more each day."

Giambi was named the American League's most valuable player in 2000 and AL comeback player of the year in 2005.

The five-time all-star is a career .291 hitter with 357 HRs, 1,167 RBIs and 1,036 runs in 1,667 games over 13 MLB seasons for the Oakland Athletics and Yankees.

Giambi is in the sixth year of a seven-year, $120-million US contract he signed with New York on Dec. 13, 2001.
