TAMPA, Fla. -- Nick Swisher sounds like he is volunteering to deliver the Yankees' pies this season.

Swisher beamed when he was told of manager Joe Girardi's comments, in which he said that Swisher might be the likeliest choice to take over A.J. Burnett's practice of smashing teammates with whipped cream-filled towels after walk-off hits.

"You know, A.J. was a good buddy of mine, and he was a good buddy of all the guys in here," Swisher said. "I'm sad to see him go, and wish him the best of luck. We're going to have to keep something going, man, because people in New York want pie! You know, let's just keep it going."

It was pointed out that someone else would have to assume the responsibilities if Swisher was the one notching the walk-off hit.

"That's what I'm saying," Swisher said. "Can you pie yourself?"

Mo throws first bullpen session of spring

TAMPA, Fla. -- No Yankees player has a better idea of what his body needs to get ready for the season than Mariano Rivera, which is why the team permits the legendary closer to dictate his own spring workload.

As he enters his age 42 season, Rivera may be moving a bit ahead of schedule. Rivera volunteered to pitch his first bullpen session of the spring on Sunday morning, and even manager Joe Girardi wondered aloud if Rivera was doing so earlier than normal.

"It's pretty much knowing your body and what you need to do," Rivera said. "That's definitely what I try to do."

Under a passing early-morning shower, Rivera threw 22 pitches beyond the right-field wall to catcher Gustavo Molina as bullpen coach Mike Harkey stood in without a bat. Rivera said that he only threw "maybe four times" over the winter.

The rest of the Yankees have been throwing their bullpen sessions on a covered practice field beyond the third-base side of George M. Steinbrenner Field, but Rivera -- a creature of habit -- opted to throw in the old uncovered "six-pack" down the right-field line, because he always has.

"He looked fine. He looked like the Mo that you're used to seeing this time of year," Girardi said. "I'm pretty sure that he knows what he needs to do."

Dickerson clears waivers, stays in Yanks camp

TAMPA, Fla. -- The Yankees announced on Sunday that outfielder Chris Dickerson cleared waivers and was outrighted to the roster of Triple-A Scranton/Wilkes-Barre.

Dickerson, 29, will remain in Major League camp. Because Dickerson was out of Minor League options, there was some concern that the Yankees would lose him if they attempted to send him down this spring.

The move clears a space on the 40-man roster, which the Yankees will likely use to add infielder Eric Chavez. Chavez agreed last week to a one-year, $900,000 contract with the club and has participated in two days of workouts, but has not been officially put on the roster.

Dickerson batted .260 with one home run and seven RBIs in 60 games for the Yankees last season, also playing in 57 games at Triple-A.

Bombers bits

• An MRI performed on Yankees catcher Austin Romine's back revealed inflammation, and manager Joe Girardi does not seem concerned that his soreness will present a serious setback.

"Because it's Spring Training, we can take our time and make sure it's knocked out," Girardi said. "He'll be down a little bit, but it's something that he'll get back from."

Girardi has said that Francisco Cervelli is the front-runner to serve as Russell Martin's backup catcher this year, with Romine likely heading to Triple-A as the starting catcher.

• Girardi said he was unconcerned by several wild throws made during pitchers' fielding practice, noting that hurlers sometimes have difficulty throwing to the bases this early in the spring.

• Yankees pitchers CC Sabathia and Michael Pineda are scheduled to throw their first batting practice sessions of the spring on Monday at 8:30 a.m. ET. Girardi said that his biggest concerns are "that they're able to throw strikes and they don't hit people."
