Arlington, TX (SportsNetwork.com) - Texas Rangers pitcher Ross Detwiler was placed on the 15-day disabled list among a flurry of moves made by the team prior to Sunday's game against Cleveland.

The Rangers also promoted pitchers Tanner Scheppers and Ross Ohlendorf from Triple-A Round Rock and designated reliever Kyuji Fujikawa for assignment.

Detwiler experienced soreness following his start Thursday against Kansas City and has been diagnosed with inflammation in his left shoulder.

The southpaw has mostly struggled during his first season in Texas, having gone 0-5 with a 6.95 ERA in seven starts. Opponents have hit a robust .336 off Detwiler over that stretch.

Texas has yet to announce who will take Detwiler's next scheduled start, slated for Wednesday at Boston.

Scheppers, one of the Rangers' top relievers in 2013 who missed most of last season due to injury, was sent to the minors on April 27 after allowing five runs in four innings over five appearances. The hard-throwing righty threw 7 2/3 scoreless frames in seven outings at Round Rock, however.

Ohlendorf went 2-1 with a 4.35 ERA in nine relief appearances at Round Rock. The 32-year-old was an 11-game winner with Pittsburgh in 2009 but has not pitched in the majors since September of 2013.

Fujikawa surrendered three runs in 1 2/3 innings over a pair of games since being activated from the 15-day DL on Thursday. The Japanese veteran owns a 5.74 ERA over 29 appearances in the majors.
