TAMPA, Fla. -- Vice President Joe Biden was on the infield grass at George M. Steinbrenner Field on Wednesday, watching the Yankees workout before their game against the Blue Jays.

Wearing a Yankees cap, Biden chatted with manager Joe Girardi and guest instructors Goose Gossage, Ron Guidry and David Wells, among others.

While Biden spoke with players and coaches for about 30 minutes, most of the Yankees were working on fielding bunts and pickoffs, doing their normal routines in front of an audience that also included several Secret Service members.

Biden is scheduled to attend a fundraiser for U.S. Senator Bill Nelson (D-Fla.) on Wednesday evening in Tampa. He was in Orlando, Fla., earlier in the day, discussing high-speed rail projects with donors.

Granderson might not be ready for Opening Day

TAMPA, Fla. -- The Yankees may have to produce an Opening Day lineup without Curtis Granderson, as the center fielder mends a strained interior oblique muscle.

Granderson said Wednesday that he won't be surprised to see the Yankees use a cautious stance with his recovery, which might knock him out of the team's March 31 opener at Yankee Stadium against the Tigers.

"The talks I had with [general manager Brian] Cashman were, 'We just need you ready,'" Granderson said. "It doesn't matter about Opening Day, as exciting as that is and as important as that is. It's one game out of this whole 162 game season."

Manager Joe Girardi remains optimistic that Granderson could be available. If not, Brett Gardner could slide to center field with Andruw Jones taking over in left field.

"I believe that there's a chance that [Granderson is] going to play Opening Day," Girardi said.

Granderson strained his oblique in his last swing of batting practice on Tuesday in Sarasota, Fla., the spring home of the Orioles.

The 30-year-old had an MRI Wednesday and has been receiving treatment for the injury from head athletic trainer Gene Monahan.

"I definitely don't want it now, but it's better now than during the season," Granderson said.

Granderson is the fourth Yankees player to have an oblique issue this spring, shades of a rash of hamstring injuries in 2007 that eventually led to the dismissal of Marty Miller, the team's director of performance enhancement.

This spring, right-handed pitchers Joba Chamberlain and Sergio Mitre have dealt with oblique issues, as well as outfielder Greg Golson.

"I'm still puzzled as to what and why; what's going on," Granderson said. "I'm now the fourth guy with it. You can't put a finger on it."

Girardi said that the Yankees discussed the oblique issue after Granderson's injury and have not radically changed their program from 2010.

"It's really not much different from what we did last year," Girardi said. "For whatever reason, it's happening this year. Maybe it's the heat. It's hot, guys get dehydrated. It could be part of it."

Golson among Yankees' roster cuts

TAMPA, Fla. -- The Yankees continued to trim their roster on Wednesday, optioning outfielder Greg Golson to Triple-A Scranton/Wilkes-Barre.

Manager Joe Girardi said that the team wants Golson to see more playing time. He was sidelined from March 7 until Tuesday with a strained oblique, appearing in each of New York's last two games.

Girardi said that Golson could be a candidate to be on the big league roster in the event Curtis Granderson is not available for Opening Day due to his oblique strain.

"We want him to go get some at-bats," Girardi said. "He's been kind of behind, and I don't want him getting one at-bat a day here."

In other moves Wednesday, New York also reassigned catcher Jose Gil, outfielder Jordan Parraz and infielder Jorge Vazquez to Minor League camp.

The Yankees also announced that infielder Brandon Laird, infielder Kevin Russo and outfielder Melky Mesa will report to Minor League camp. Those players had been previously optioned to Triple-A on March 16.

Girardi has said that he plans to have all roster decisions finalized by Monday. After Wednesday's game, New York also optioned left-hander Steve Garrison and right-hander Ryan Pope to Double-A Trenton. Right-hander Eric Wordekemper was also reassigned to Minor League camp.

Swisher day to day after hitting ball off foot

TAMPA, Fla. -- Nick Swisher was hobbled briefly in Wednesday's 5-3 Yankees victory over the Blue Jays after fouling a ball off himself.

Swisher smashed a ball off his left instep while batting in the sixth inning against Toronto's Jo-Jo Reyes, stumbling back toward the Yankees' dugout in pain.

After being examined by head athletic trainer Gene Monahan, Swisher stayed in the game and finished his at-bat, lining hard into a double play.

"Hopefully it's just day to day," said manager Joe Girardi, who said Swisher would come in for further treatment on Thursday's off-day.

Swisher left the game after the inning and was replaced by Greg Golson in right field, but Girardi said he was planning to do that anyway.

Bombers bits

The Yankees claimed left-hander Jose Ortegano off waivers from the Braves on Wednesday and optioned him to Triple-A Scranton/Wilkes-Barre. He will report to Minor League camp. In 2010 with Triple-A Gwinnett and Class A Myrtle Beach, he combined to go 5-15 with a 5.98 ERA. ... A.J. Burnett allowed four runs in 5 2/3 innings on Wednesday pitching to a lineup of Class A Phillies batters. He surrendered six hits, walked three and struck out eight in a 94-pitch outing. ... Mariano Rivera made his fourth spring appearance on Wednesday, firing a perfect inning. ... Freddy Garcia will pitch in a Minor League game on Thursday afternoon in Tampa.
