GLENDALE, Ariz. -- Tony Gwynn Jr. is breathing a sigh of relief, because Tony Gwynn Sr. is already doing radio interviews, less than a week after five doctors performed an intricate 14-hour operation to remove a cancerous tumor in his mouth.

"The doctors did an unbelievable job," said the outfielder and son of the Hall of Famer, now the baseball coach at his alma mater, San Diego State University. "When he came out of the surgery, he said, 'All right, I made it.' Last time he had surgery, he couldn't talk."

The elder Gwynn, 51, blames his rare form of cancer on the use of smokeless tobacco when he played. The cancer was on the same side of his mouth where he would place the tobacco.

He underwent surgery for a cancerous tumor in the same spot 18 months ago. This time, surgeons grafted a nerve from his shoulder to replace a nerve that had become intertwined with the tumor.

"The second time, you feel the odds are more against you, from the son's perspective," said Gwynn Jr. "God works in mysterious ways."

Belisario on time and in shape

GLENDALE, Ariz. -- On Tuesday, for the first time in his four Spring Trainings with the Dodgers, Ronald Belisario reported to camp on time.

In fact, Belisario has been working out at Camelback Ranch for several weeks, having obtained the work visa that eluded him throughout 2011.

There's still the 25-game suspension he must serve for violating MLB's drug policy; that takes effect when the season begins. He will be allowed to play in Spring Training games, general manager Ned Colletti said, and can participate in a 10-game Minor League rehab assignment before he returns from his suspension.

Belisario is also one of five Dodgers out of options, meaning he cannot be sent back to the Minors without clearing waivers and made available to every other club.

"He looks in good shape," manager Don Mattingly said of the right-handed reliever, who was a key part of the 2009 bullpen but has been plagued by legal and substance problems since. "Everybody knows he's had problems, but he's here, and that's a good sign."

Belisario's problems in 2010 led to the free-agent signing of Matt Guerrier and the acquisition of Blake Hawksworth. The Dodgers also added Todd Coffey when Hawksworth was slow recovering from elbow surgery.

Mattingly said that because his bullpen is deep, he's not counting on Belisario.

"He's back to starting over," Mattingly said. "This is a new start for him, and we'll just see. We know the demons. We've got to see what he's got. He's been a good guy. It's not like he's a bad guy, but to this point, it's tough to count on him when you build a club, and three of four seasons he can't even get to camp."

Kemp, Kershaw weigh in on ownership

GLENDALE, Ariz. -- Two of the most interesting comments about the auction to find a new owner on Tuesday came from two of the team's highest-paid players.

"Two billion dollars?" an incredulous Matt Kemp said when told that the sale price could reach that lofty level. "I thought I was rich."

And he is, having signed an eight-year, $160 million contract.

Clayton Kershaw was asked if he had any favorites in the bidding war and, naturally, mentioned Joe Torre.

"He's the only one I know," Kershaw said of his former manager. "That would be cool."
