NEW YORK -- Yankees outfielder Chris Dickerson underwent about 15 minutes of memory tests on Friday, reporting that he is feeling better after suffering a concussion during Wednesday's series opener at Baltimore.

Dickerson was drilled on the helmet by the Orioles' Mike Gonzalez in the 15th inning of the Yankees' 4-1 win at Camden Yards, and a CT scan taken at a local hospital revealed the concussion.

Dickerson expects to be able to avoid Major League Baseball's new seven-day disabled list for concussions, though Yankees manager Joe Girardi said he would need to confer with team physician Christopher Ahmad and head trainer Gene Monahan.

"Unless I get lost on the way home or forget what city I came from, I should be fine," Dickerson said.

Dickerson said that Monahan put him through a battery of exams that included recognizing shapes and images, as well as judging reaction time. He planned to resume swinging a bat on Friday.

Hip pain-free, A-Rod forgoes checkup

NEW YORK -- Alex Rodriguez had said there was no urgency to have a routine checkup on his right hip since he was feeling no discomfort, and the Yankees clearly agreed.

Rodriguez had been tentatively scheduled to have team physician Christopher Ahmad take a look at the hip on Friday, but the Yankees' late return from Baltimore washed away those plans.

"It was cancelled," manager Joe Girardi said. "We've had a number of late nights in the last four or five days, and he's feeling fine."

Girardi said that he did not know when Rodriguez's exam would be re-scheduled to take place.

Rodriguez said in Baltimore that hitting coach Kevin Long suggested the examination, noting that the slugger had been less inclined to use his lower half at the plate than usual.

The 35-year-old Rodriguez had a serious procedure on his hip in March 2009 and has regularly been seen after each season by Vail, Colo.-based specialist Dr. Marc Philippon, who performed the surgery.

"Checkups are going to be part of the rest of my career," Rodriguez said. "We're doing it to be very proactive. I wouldn't be surprised if there's another one in October or January.

"Again, we'll be sitting here next year talking about that. We just want to make sure. That's a certain box, and we want to check it off."

Swisher hopes he's turned a corner

NEW YORK -- It took Nick Swisher several attempts on Friday to correctly deliver the saying his father always told him:

"Sailors never perfected their craft sailing smooth water," Swisher finally said, with a laugh.

Swisher is hoping a big performance in Thursday's 13-2 Yankees win at Baltimore will get him over the hump at the plate.

Swisher's two-hit, four-RBI night helped him snap an 8-for-44 (.182) skid that saw his average sink to .215.

Some pregame one-on-one time in the batting cage with hitting coach Kevin Long helped Swisher limit his leg movement, he said -- a step in the right direction.

"I've got a feeling they're coming, and I've just got to kind of wait for that," Swisher said of his missing hits. "But right now, when you're kind of going through these tough times, you learn a lot about yourself."

Both Swisher and manager Joe Girardi are hoping his three-run double in the first inning on Thursday is a sign of more things to come for the always-sunny right fielder.

"I think all hitters carry at-bats with them from time to time, or days with them from time to time, or streaks," Girardi said. "But yeah, obviously, it can be. Sometimes, it can be a big hit like that; other times, it can just be a blooper."

Yanks open museum exhibit honoring 'Boss'

NEW YORK -- The Yankees opened a new exhibit on Friday honoring late principal owner George M. Steinbrenner at the Yankee Stadium museum.

The exhibit, located on the 200 level in right field, aims to capture Steinbrenner's "dedication to winning, his motivation to take the Yankees to the top of baseball and his quiet generosity." It features all seven of The Boss' World Series rings, his three American League championship rings from years the Yankees did not win the Fall Classic, his two Olympic rings, his 1977 All-Star Game ring and his '67 Rose Bowl ring.

Other mementos include Steinbrenner's "Lead, Follow, or Get the Hell Out of the Way" sign from the original Yankee Stadium, Associated Press photos and artwork from late New York Daily News cartoonist Bill Gallo, in addition to several other awards and items given to Steinbrenner during his tenure as the Yankees' owner.

Bombers bits

Eric Chavez said that he will begin to put pressure on his fractured left foot this week, and he hopes to resume running soon. Chavez said he feels no pain when walking. ... Right-hander Phil Hughes was scheduled to meet with team physician Christopher Ahmad on Friday to determine his next step of rehab. Hughes made throws from 90-100 feet on Thursday and felt good. ... Lefty reliever Pedro Feliciano said his rehab is coming along well and he expects to resume throwing in early June. Since he is on the disabled list, Feliciano said he would hope to make good on his promise to strike out the Mets' Ike Davis in July. "He's hurt; I'm lucky," Feliciano said.
