SAN DIEGO -- The road show to Hank Aaron began on Monday for Barry Bonds, with Padres fans predictably booing him and yelling taunts. It wasn't any worse than Opening Day last year at Petco Park, when a fan famously threw a toy syringe at Bonds' feet and he picked it up as he jogged off the field.

Bonds said he wasn't and isn't bothered by any of it, despite the obvious implication that he took steroids.

"Why? Why should it bother me?" said Bonds, prior to playing his first road game of the season. "People come to the game to have fun, you've got hecklers out there, you know, it's been in baseball forever. It's going to be out there long after I'm gone. So you know what, you can have fun with it, you can (let it) go in one ear and out the other, or you can get sensitive and let it affect you.

"It doesn't. It doesn't affect anything I do on that field. Because I've got a job to do no matter what."

As in the past few seasons, Major League Baseball has a traveling security team following Bonds on the road this year. If anything gets thrown on the field. Bonds is instructed not to touch it -- including syringes of any kind.

"I didn't know what it was at first," Bonds recalled. "I just took it off the field. Then I was told by Major League Baseball don't touch anything that comes on the field."

No hammering Hank

Bonds said he wasn't disappointed to hear that Aaron had no interest in being in person when and if his record is broken. Aaron told ESPN that he would probably be playing golf or vacationing in Europe with his wife when Bonds breaks his record.

"If he has other plans, other things, to do, I respect that," Bonds said. "He's his own man, he can do what he wants to do. No hard feelings.

"Now if Willie (Mays) wasn't there, I'd be disappointed. Because that's my godfather. I'd be real (ticked). My dad, he'll be there too, in spirit."

Sweeney starting rehab

Mark Sweeney will report to Arizona today on a rehab assignment and will start in extended spring games for at least the next two days. The veteran pinch hitter can be activated on Friday, but the Giants have left him in the dark about his status.

It's possible the club would activate Sweeney only if it can squeeze first baseman Lance Niekro through waivers. In any event, Sweeney isn't guaranteed a roster spot.

"We'll see," general manager Brian Sabean said. "He does certain things. The team needs certain things. You have to do what's best for the organization. He understands that, and he's been great about it."
