Persistent back spasms keep Hardy out

NEW YORK -- Orioles shortstop J.J. Hardy was not in Monday's starting lineup against the Yankees, riding the bench for the third time in four games as he continues to deal with nagging back spasms.

"Very, very frustrating," Hardy said of the injury, which forced him out of the lineup on Friday and again on Sunday, though his latest spasms are in a different spot in his lower back. "It was probably the healthiest Spring Training I've had yet, with everything feeling good, and then this came out of nowhere."

Hardy took about 20 grounders at Comerica Park before Sunday's game but had to leave before he got a chance to swing the bat, as his lower back locked up. Without him -- and with third baseman Manny Machado on the disabled list -- Ryan Flaherty has moved to shortstop and Jonathan Schoop to third.

"We just want it resolved now," manager Buck Showalter said of the injury affecting Hardy, who has not been scheduled for any tests. "A lot of guys have stuff that they play with that we don't make note of, but this one just hampers him. ... I guess he counts ground balls; it was his 21st ground ball when it just kind of locked up on him. He's better today than he was yesterday, so we will see what the game brings, see what he feels like by game time, if he's available."

Hardy reported feeling slightly better on Monday morning after his first round of treatment and reiterated what he said in Detroit, that it's just a waiting game.

"I told everyone the other day that once the muscles relax, then it happens really quick and you get better," Hardy said. "But you've got to get those muscles to relax first."

O's land righty Guilmet; Reimold to 60-day DL

NEW YORK -- The Orioles made a minor trade on Monday, acquiring right-handed pitcher Preston Guilmet from Cleveland in exchange for Minor League outfielder Torsten Boss.

The O's optioned Guilmet to Triple-A Norfolk and moved outfielder Nolan Reimold from the 15-day disabled list to the 60-day DL to clear a roster spot. Manager Buck Showalter said prior to Monday's game against the Yankees that Reimold had not been taking part in baseball activities and had just been receiving treatment on his neck.

Guilmet, 26, was drafted by Cleveland in the ninth round of the 2009 First-Year Player Draft, and he posted a 1.68 ERA with 20 saves in 49 games for Triple-A Columbus in 2013.

"[He] has command of his fastball, slider and split-finger, which he mixes to get hitters out," O's executive vice president Dan Duquette said of Guilmet in a text message. "We expect he'll contribute to the [Major League] team this season given his track record and experience closing games."

Last season in Columbus, Guilmet averaged 10.1 strikeouts per nine innings and appeared in four games for the Indians, posting a 10.13 ERA in 5 1/3 innings.

Chen need not look far for inspiration from O's

NEW YORK -- Call it the Chris Tillman effect.

Following the Orioles right-hander's dominant 8 1/3 innings in Sunday's 3-1 win at Detroit, his teammates certainly took notice.

"We all can learn from him," said left-hander Wei-Yin Chen, who will take the ball at Yankee Stadium on Tuesday afternoon. "He inspires me; he inspires me a lot. After watching him pitch, in my next start, I'd like to get a better feel for all of my pitches."

Chen, the O's No. 3 starter, is a key part of the rotation, and he's coming off a disappointing season debut in which he lasted 5 2/3 innings and gave up four runs on 12 hits.

"Basically, it's the breaking ball," Chen, through his interpreter, said of what needs to change against the Yankees. "It's not working 100 percent the way i want it to be. Hopefully I can get it to be better."

Worth noting

• Left-hander Johan Santana was slated to throw a two-inning sim game at the O's spring facility on Monday, with prospect Dylan Bundy throwing a 30-pitch bullpen session.

• When asked about Yankees captain Derek Jeter and Monday's home-opener festivities in New York, Showalter reminded reporters there's a pretty good history at Camden Yards, too.

"I'm pretty proud of our people and our statues, OK?" Showalter said. "We've got some statues, too."
