MINNEAPOLIS -- Baltimore Orioles outfielder Adam Jones left Tuesday's game against the Minnesota Twins and was transported to a hospital with what the Baltimore Sun reported as shortness of breath and mild chest pains.
Early Wednesday morning Jones hit Twitter to say he was doing fine.
"Back from hospital. Wasn't as serious as it sounded," Jones said. "Glad everything is in order. Appreciate the support and well wishes. Back at it manana."
The Orioles, who described Jones' condition as an illness when he left in the second inning, believed his condition was muscular in nature and not cardiopulmonary, the Sun reported on its website. A Minneapolis radio station reported the Orioles called 911 from their dugout, but the Sun reported the call was simply part of the stadium's standard operating procedure to summon the Twins' team doctor rather than an emergency call.
Jones started in center field as usual and struck out in his first at-bat before being replaced by Matt Angle, who pinch-hit for Jones in the second inning.
Orioles manager Buck Showalter declined to say what was bothering Jones and wasn't sure how long he would be at the hospital.
"After talking with a few people, he was feeling a little down and just weak," Showalter said. "Then after his first at-bat and everything, it didn't get any better. Didn't like what he was describing, so we decided to get him out of there and let the doctors take a look at him.
"They're still looking into it, haven't really been able to nail down. We just want to rule a lot of things out to be on the safe side. We're going to let them do some more tests at the hospital," Showalter said.
Jones has played in 124 of Baltimore's 126 games this season, batting .297 with 22 home runs and 77 RBIs. Angle was recalled earlier in the day from Triple-A Norfolk when the Orioles designated slumping outfielder Felix Pie for assignment.
