SURPRISE, Ariz. -- Reliever Juan Carlos Oviedo, who is in camp on a Minor League contract, is dealing with biceps tendinitis in his right arm and will be sidelined for a couple of days.
Oviedo is an experienced closer who had 92 saves for the Marlins from 2009-11, when he was known as Leo Nunez. But he missed all of 2013 season because of Tommy John elbow reconstruction surgery and had a 3.69 ERA in 32 games for the Rays last season.
He is trying to win a spot in the Rangers' bullpen but has a 4.91 ERA in four Cactus League appearances. An arm issue could be a significant setback in his chances of winning a spot in the highly competitive bullpen race.
"We'll just have to see how his arm responds in the next couple of days," assistant general manager Thad Levine said.
