Melky Cabrera has expressed remorse for cheating, lying and letting down the city of San Francisco while with the Giants.

Cabrera returned to AT&T Park for the first time since receiving a 50-game suspension last Aug. 15 following a positive testosterone test.

"That was an ugly time for me and my family," Cabrera said "I feel very sorry for what happened. I regret what happened. It's in the past. ... That was 2012. Now, it's 2013 and I'm focused on playing baseball."

Cabrera received loud boos when he came to the plate in the first inning.

"Melk doesn't say much, all he does is smile," John Gibbons said. "I'm sure he's looking forward to it. I don't know what the reception will be. He's just that guy who shows up and he's a fun-loving guy, he loves to play baseball and he's good at it. I'm sure he listens to the kind of reaction he gets. He's got the same demeanor every time."
