Tigers reliever Nathan feels 'pop' during rehab appearance

DETROIT (AP) Tigers reliever Joe Nathan left a rehab outing Wednesday after pitching less than an inning, and Detroit manager Brad Ausmus says the 40-year-old right-hander felt a ''pop'' while throwing a fastball.

Ausmus says Nathan was being evaluated. He was pitching for Triple-A Toledo while trying to work his way back from a right elbow strain.

Nathan struck out the only batter he faced in Detroit's season opener this month, but he hasn't pitched in the majors since. His stint on the 15-day disabled list began April 7.

The Tigers signed Nathan before last season, and he struggled in 2014, finishing with 35 saves in 42 chances but posting a 4.81 ERA.

Joakim Soria is the closer for Detroit and has converted all five of his chances this season.
