Marquis will start for the Reds on Monday against the Rockies, MLB.com's Mark Sheldon confirms. Marquis has now taken three straight losses, giving up 15 earned runs on 21 hits over that span. To make matters worse, he hasn't given the Cincinnati bullpen much relief, failing to make it out of the fourth inning in back-to-back outings. Despite the struggles, the 36-year-old right-hander will get at least one more turn in the rotation, but another poor outing could force manage Bryan Price into a decision.
