CLEVELAND — The Texas Rangers offense continued its downward spiral on Sunday, and did something that hadnt been done since 2009.The Rangers were shut out for a second consecutive game in a 6-0 loss to the Cleveland Indians at Progressive Field. The Indians completed a three-game sweep of the Rangers in Cleveland for the first time since 1980.The Rangers, who have lost eight of 10 since the All-Star break, dropped six games back of Oakland in the American League West race after the A's defeated the Angels 10-6 Sunday.Alexi Ogando made his second start since coming off the disabled list, and opened with four scoreless innings. He couldnt get through the fifth, though, allowing a run on an RBI single to Jason Kipnis.Robbie Ross entered and got the final out of the fifth, but then gave up three runs in the sixth. Yan Gomes had a two-out RBI single, and Michael Bourn followed with a two-run double.That was more than enough for the Indians and starter Ubaldo Jimenez. Jimenez held the Rangers to two hits over eight innings, and Vinnie Pestano pitched a scoreless ninth.
