The Rays will go for a sweep in a Sunday matinee against the Orioles, and will do so with backup C Shawn Riggans behind the plate.

Manager Joe Maddon said he wanted to give C Dioner Navarro a day off because the All-Star experienced some soreness following Saturday's game. On Saturday, in his first start in four days (due to sore hamstrings), Navarro went 1-for-4 with a double, and was also thrown out at the plate trying to score from second.

It appears likely that Navarro won't return behind the plate until Wednesday, as Riggans has become Matt Garza's personal catcher, of sorts, and Maddon said he was learning toward having Riggans catch the right-hander in Tuesday's series opener with the Yankees.

There's no word yet on September callups, but Maddon said the number of callups will be small, and come in "two waves." Maddon joked another "callup" will be closer Troy Percival, who will most likely be activated on Tuesday from the disabled list. With Navarro's latest hamstring issues, expect another catcher to get called up from Triple-A, with veteran Mike DiFelice a possibility.
