The Pittsburgh Pirates and Detroit Tigers will have their aces on the mound Thursday, though apparently not in the same game. The teams will play a doubleheader in Detroit due to a Wednesday rainout. Unless the managers change their minds overnight, the day game will feature Tigers ace Tarik Skubal, while Pirates ace Paul Skenes will go in the nightcap. Skubal (7-2, 1.99 ERA) presents a monumental challenge wherever he pitches, but he is especially stingy at Detroit’s Comerica Park.
