CHICAGO (AP) -- The Pittsburgh Pirates have placed left-handed reliever Joe Beimel on the 15-day disabled list with left elbow inflammation.
Lefty Daniel Moskos was recalled from Triple-A Indianapolis to take his roster spot Saturday.
Beimel was given Thursday off after experiencing discomfort, but his arm felt worse against the Cubs on Friday, when he allowed Alfonso Soriano's two-run homer in the ninth.
Pirates manager Clint Hurdle said that "this was more than discomfort ... this was pain."
Beimel was sent to Pittsburgh to be examined by team doctors.
Moskos made five appearances for the Pirates from April 30-May 15. Pittsburgh's No. 1 pick in 2007, he allowed two hits and an unearned run in 4 2-3 innings in his first major league stint.
