Angels right-hander Garrett Richards will oppose White Sox right-hander Hector Noesi in Game 1, with both starters simply getting moved back one day, and Angels righty Jered Weaver will oppose White Sox righty Scott Carroll in Game 2, as originally scheduled.
Tyler Skaggs, who has been on the disabled list since June 10 with a strained right hamstring, will be activated to start Wednesday's series finale, giving the Angels a six-man rotation that is now necessary because of the doubleheader and because they don't have another day off until the All-Star break, which begins July 14.
That means Hector Santiago and Matt Shoemaker will both remain in the rotation at least one more time through the order.
"On the back side is where you need to absorb [a doubleheader], like when you need to bring another starter back into the mix," Angels manager Mike Scioscia said. "I think we're OK there, because we've had Shoe and Santiago getting starts. So we should be able to absorb it on the back end, and that's as important as anything."
