Sammy Sosa isn't interested in answering the lingering questions about steroids. After a year out of baseball, the slugger has more pressing issues with the Texas Rangers.

"I don't want to talk about whatever happened in Congress," Sosa said yesterday in Surprise, Ariz. "This is not my problem. I've got to make the team."

Two years after being among several players who testified before a congressional committee looking into steroid use in professional baseball, Sosa is trying to make a comeback and has a minor league contract with his original team.

But he's still fielding the same questions that dogged him when he left the game after the 2005 season with the Baltimore Orioles.

"I don't want to talk about that," Sosa said. "Let's talk about baseball."

The former NL MVP and seven-time all-star, fifth with 588 career home runs, took part in the Rangers' first full-squad workout.

If he makes the Rangers' 40-man roster, Sosa would get a $500,000, one-year deal and could earn more than $2 million in performance bonuses. But he said he's not coming back because of money or the pursuit of 600 home runs.

"This is my life," he said. "I'm not coming back for 12 home runs. I'm coming back for more than that."

· GIANTS:Even if Barry Bonds is not an all-star this season, owner Peter Magowan expects the slugger to take part in festivities for baseball's summer classic in his home ballpark.

Magowan hopes that Bonds's godfather, Hall of Famer Willie Mays, will be a big part of the July event. Yet Magowan would rather No. 25 is in uniform and playing for the NL roster and World Series-winning Manager Tony La Russa.

"If Willie is going to get honored, as I think he will, Barry will have some role to play there," Magowan said.

· YANKEES:Mariano Rivera sailed through his first batting practice session.

The closer threw 35 pitches to a hitting group that included Derek Jeter, Johnny Damon, Bobby Abreu and Robinson Cano.

"Mariano was fine," Manager Joe Torre said.

· DIAMONDBACKS:Randy Johnson pitched off a mound for the first time since back surgery in October and said after his private bullpen session that he felt fine. The Big Unit threw 25 fastballs and said he was "pretty free and easy."

· BLUE JAYS:Jo Matumoto, a 36-year-old left-hander who pitched for Brazil's national team, agreed to a minor league contract and was invited to spring training.
