NEW YORK -- Orioles closer Jim Johnson has thrown two bullpen sessions since being released from the hospital on Friday, and he appeared in Monday's series-opening 2-1 loss to the Yankees, before which he said he'd be ready to go if manager Buck Showalter needed him.

Johnson entered in a non-save situation and worked a 1-2-3 bottom of the eighth, getting Derek Jeter, Curtis Granderson and Alex Rodriguez to ground out.

"I feel back to normal," Johnson, who spent four days at a Baltimore hospital with food poisoning, said before the gaje. "My pants fit a little bit looser."

Johnson hadn't appeared in a game since April 22, when he picked up his seventh save of the season in the Orioles' 3-2 win over the Angels. The right-hander admitted on Monday afternoon that the first time he threw after being discharged from Saint Agnes Hospital, he didn't feel right, but Sunday's session was an improvement.

Showalter said before the game that he wouldn't try to ease Johnson back in with a no-pressure situation, adding that he'd try to use the righty as he has all year, in the closer's role.

Johnson -- who has converted his last 15 save opportunities, dating back to last season -- told Showalter he was available on Sunday, but he wasn't used as Baltimore rallied to score five runs in the ninth inning and defeat the Oakland A's, 5-2.

"He wasn't too happy with Buck yesterday," Showalter said with a grin. "[Johnson is] ready to go. He's eating normal food."

Showalter must wait for 1,000th victory

NEW YORK -- Manager Buck Showalter is on the cusp of a milestone, as the Orioles skipper entered Monday's series opener against the Yankees -- a 2-1 Baltimore loss -- one win shy of 1,000 career managerial victories, a mark Showalter's two children have made him aware of, the manager said.

When asked if there would be any significance to reaching the 1,000-win mark against the New York Yankees -- the organization with whom he got his first career managerial win, on April 7, 1992 -- Showalter said he doesn't look at it that way.

"[It] just reminds you of what an honor it is to be in the big leagues and have a chance to do it for a while," said Showalter, who is in his third year with the Orioles and entered Monday with a career record of 999-957 in 14 seasons with the Yankees, Rangers, D-backs and O's. "To be around so many good players, good general managers, good owners, good organizations -- not a day goes by I don't wake up and realize what an honor it is to be in the big leagues."

Showalter, who notched his first win on Opening Day in 1997, recounted the final out of that game -- which featured Scott Sanderson beating Roger Clemens' Red Sox, 4-3 -- and said he remembers all of the losses pretty vividly, too.

"I remember walking up the runway and realizing you had about 45 seconds before you had to figure out a way to win the next game," said Showalter, who is seventh among active managers in wins. "[I] had some good players, had some good people."

Worth noting

• Second baseman Brian Roberts is with the Orioles in New York as he continues to travel on road trips and work out, progressing toward his return from a concussion. Roberts was one of several O's players out for early extra batting practice at Yankee Stadium on Monday, along with Nick Johnson, Mark Reynolds, Ryan Flaherty, Wilson Betemit, Nick Markakis, Ronny Paulino and J.J. Hardy. There is still no timetable for Roberts' return or any indication of when he could begin a rehab assignment.

• Right-hander Dylan Bundy -- the No. 10 prospect in baseball, according to MLB.com -- tossed four scoreless innings for Class A Delmarva on Monday night in a start against the Asheville Tourists, the Rockies' affiliate.

Bundy allowed his first hit as a pro and issued a walk, but he faced the minimum batters thanks to a pair of double plays. The 19-year-old Bundy has thrown 17 scoreless innings to start his professional career, recording 25 strikeouts and two walks.

• Orioles lefty Zach Britton, sidelined with a left shoulder impingement, threw his second bullpen session in extended spring camp on Monday morning and will throw another one on Wednesday before pitching in an extended spring simulated game on Saturday.

The 24-year-old Britton threw 50 pitches and said afterward that everything felt great. Britton's schedule is largely up in the air, depending on how he feels, but an early-June return seems to be a pretty good estimate at this point. Britton tossed his first bullpen session -- around 35 pitches -- on Friday, throwing mostly fastballs and mixing in a few changeups.

• Orioles left-hander Tsuyoshi Wada, who flew to Los Angeles on Sunday to meet with Dr. Lewis Yocum for a second opinion on his ailing left elbow, will undergo further tests, the results of which the club expects to have on Tuesday.
