A day that started bad for the Rays with news that Alex Cobb was placed on the disabled list didn't get any better with a 12-4 loss to the Reds.
The loss of Cobb further thins their pitching depth. And the Sunday performance LHP Cesar Ramos, making his first start in place of injured Matt Moore, didn't do much to calm any concerns as he lasted only into the third inning, allowing four runs.
The Rays ran through five more pitchers after that, including veteran Erik Bedard, who is likely to join the rotation and make his first start on Thursday against the Yankees.
The Rays were down 7-2 after three innings - with Ramos giving up a bases loaded double to Zack Cozart and a two-run bomb to Joey Votto, and reliever Brandon Gomes a three-run shot to Devin Mesoraco - and the game didn't get much closer after that.
There were a couple highlights for the Rays -switchhitter Ben Zobrist homering from both sides of the plate in a game for the first time, with a pair of two-run homers, and catcher Ryan Hanigan making two putouts on the same play in an odd second-inning sequence.
Reliever Josh Lueke gave up a grand slam to Chris Heisey in the eighth for the final margin.
Having split the first six games on this road trip, the Rays not move on to Baltimore and open a three-game series against the Orioles Monday night with Chris Archer on the mound.
