"It was more designed to get Corporan back-to-back [starts]," Astros manager Bo Porter said. "After the long flight home, the 14-inning game; [Jason] Castro has been outstanding, but at the same time, I want to do everything that I can to keep him fresh throughout the course of the year."
Porter added that Castro would be back behind the plate for Sunday's series finale against the Tigers. Monday is an off-day.
"So it's like [Castro] is getting three days off in a five-day span, which is great," Porter said.
