Rays starter Alex Cobb, who entered Tuesday's outing with a 3-1 record and 1.82 ERA, cruised through the first five innings in Kansas City. And then came the sixth.

Cobb allowed four hits through the first five innings then gave up six straight in the sixth. He couldn't finish the inning and finished with four earned runs on 10 hits and no walks over 5 2/3 innings. Cobb struck out five and threw 88 pitches.

Cobb went 8 1/3 shutout innings in his last start against the Yankees and had a 14-inning scoreless streak before unraveling in the sixth Tuesday. His next start is Sunday at Colorado.
