NYM@NYY: Adams makes diving stop to end the third

NEW YORK -- There have been ups and downs through David Adams' first two weeks at the big league level, but manager Joe Girardi believes the infielder has done a nice job contributing after receiving his first chance in the Majors.

"I think he's done a pretty good job for us," Girardi said. "Third base is not his natural position, and he's played a pretty good third base. He's had some good days with the bat for us. He had a little struggle, but he came out of it [Saturday] night, which I think is always good to see. I've talked about what he's faced, and it's been mostly division rivals. He's handled himself pretty well."

Adams, 26, could be on the bubble for his roster spot now that Kevin Youkilis has been activated from the disabled list. The Yankees need to make a roster move on Monday to activate left-hander Andy Pettitte for his start against the Indians, and Adams is a possible choice to be demoted to the Minors to clear space.

If the Yankees decide to keep Adams, who offers a right-handed bat and the versatility to play third, second and first, outfielder Brennan Boesch could be optioned to Triple-A Scranton/Wilkes-Barre or the club could designate first baseman Lyle Overbay for assignment.

"I can't think about it, honestly," Adams said. "It's not up to me. At the end of the day, this is a business and whoever they decide to put out on the field is their prerogative. I can't control it. What I can control is how hard I work and the mindset that I have. That's all I can control."

Adams snapped an 0-for-14 stretch with a fourth-inning single in the Yankees' 11-1 loss to the Red Sox on Saturday, and he entered play on Sunday batting .259 with two homers and five RBIs in his first 16 big league games.

"I think everything is a work in progress, honestly," Adams said. "I'm not going to lie. By no means am I a plus, plus, plus at anything -- hitting, throwing, defense, whatever. I know there's room to improve in every category of my game and I understand that."

Dealing with dizziness, Stewart sent to hospital

BOS@NYY: Stewart scores Nix with sac fly to center

NEW YORK -- Yankees catcher Chris Stewart was sent to be evaluated at New York-Presbyterian Hospital after experiencing more symptoms of dizziness before Sunday's 3-0 loss to the Red Sox.

Stewart was originally in New York's lineup but left the field during batting practice. He said that he had a blood test and a CT scan performed, and while doctors found no evidence of a concussion, Stewart will have to return to the hospital for more tests on Monday.

"It was nothing major; very minor stuff," Stewart said. "We wanted to be cautious about it and not push it. Hopefully [Monday] works out and I'm in there."

Stewart was forced to depart Saturday's 11-1 loss to Boston in the fourth inning due to symptoms of dehydration, saying afterward that he had felt light-headed but could have finished the game.

"I've had heat exhaustion where I played in very hot weather, very humid weather, and it wore on my body," Stewart said, "but nothing to where it kind of messed with my head a little bit."

Stewart was replaced behind the plate for Sunday's game by catcher Austin Romine, who went 1-for-1. Stewart is batting .262 with three homers and eight RBIs in 32 games, and manager Joe Girardi said that it would not be prudent to go with just one available catcher on the roster for very long.

"We're a little concerned or we wouldn't have sent him for a test," Girardi said. "We're hoping he comes in [Monday] and feels really good."

If anything happened to Romine, shortstop Jayson Nix would have served as the Yankees' emergency catcher.

Girardi isn't worried about Wells' recent struggles

NYY@BAL: Wells delivers with a clutch go-ahead double

NEW YORK -- When the first moth of the season came to an end, the Yankees' trade for Vernon Wells looked like a steal. The veteran outfielder was batting .300 with six home runs and 13 RBIs at the end of April, proving to be an integral piece for an injury-depleted team.

As the season has worn on, Wells' bat has cooled off. His average has dropped from .300 to .253 over the past month, and he's currently mired in a 3-for-34 slump at the plate.

Manager Joe Girardi isn't worried about Wells' struggles at the plate, though.

"He'll come out of it. I'm not concerned about that," Girardi said after Saturday's game. "He swung the bat pretty good last night, but I think he's going to come out of it."

Wells was in the lineup on Sunday night, playing left field and batting fifth against Red Sox starter Clay Buchholz. Wells is 7-for-29 in his career against Buchholz, and he's batting .230 against right-handed pitchers this year.

"I don't remember the bad stuff. You learn from it and move on," Wells said. "That's in the past, and tomorrow is a new day, so you go out, continue battling and do whatever you can to help your team win."

Part of the reason for his struggles could be fatigue. The 34-year-old has already played in 52 games this season after playing in just 77 over a full season with the Angels last year. He's batting .253 with 10 home runs and 24 RBIs on the season.

When asked if he still thinks he's an everyday player, Wells wasted little time in giving his answer.

"Oh yeah," Wells said. "I wouldn't have it any other way."

Bombers bits

• Jayson Nix entered play on Sunday having hit safely in a season-high seven straight games since May 24, one game shy of his career high. Nix has hit .357 (10-for-28) with five RBIs and three multihit games over the stretch.

• The Yankees have been held to one run in four of their last six games entering play on Sunday, compiling 12 runs total over the span since Monday. They have been held to four runs or less in each of their five games against the Red Sox this season, their longest such streak since 1992.

• On this date in 1941, Lou Gehrig died of amyotrophic lateral sclerosis at age 37 in the Riverdale section of the Bronx.
