The Twins placed Ober on the 15-day injured list Sunday due to right elbow inflammation.
The right-hander had been on a roll, going 4-2 with a 3.19 ERA, 1.02 WHIP and 29:12 K:BB over his last seven starts and 42.1 innings heading into Saturday. That impressive run came to a screeching halt when Ober was lit up for eight runs (seven earned) on 12 hits -- including three home runs -- and one walk over 4.2 innings in a loss to Pittsburgh. The elbow issue may have been a factor, and Ober will be shelved through at least mid-June. Minnesota called up right-hander Mike Paredes from Triple-A St. Paul in a corresponding move, and if he isn't needed in relief over the next few days, he could be a candidate to replace Ober in the rotation.
