Orioles manager Buck Showalter said Chris Tillman is the leading candidate to start the first game of Saturday's doubleheader. Zach Britton will be promoted to start the second game. Tillman hasn't been heard from since being demoted at the end of May after posting a 4.69 ERA over 10 starts with the O's. He's held a 4.17 ERA in 10 starts for Triple-A Norfolk but has just a 5.8 K/9 rate. It would almost surely just be a spot start for the righty.
