AP source: Marlins' Capps undergoes MRI on sore right elbow

JUPITER, Fla. (AP) Miami Marlins right-handed reliever Carter Capps was awaiting a second opinion on an MRI of his right elbow, fearing an injury that would end his bid for the closer's job before spring training games even begin.

Capps met with a doctor Tuesday after undergoing the test, manager Don Mattingly said. Capps throws a 100 mph fastball, but he missed the final two months of last season because of right elbow soreness and sat out three months in 2014 for the same reason.

The Marlins had expected him to challenge incumbent A.J. Ramos for the closer's job, but Capps was sidelined when warming up to throw batting practice.

''He came up with a little elbow soreness the other day,'' Mattingly said. ''Obviously it's concerning any time you've got to stop a guy from throwing.''

Last year Capps had 58 strikeouts in 31 innings, and his rate of 16.8 strikeouts per nine innings was the highest in the majors among pitchers with at least 15 innings. He had a 1.16 ERA in 30 games.
