Marquez will make his next start in Friday's series opener against the Diamondbacks, Nick Groke of The Denver Post reports.
The rookie was initially scheduled to start Saturday, but he'll swap places in the rotation with Tyler Anderson. It's expected that Marquez will stick with the big club at least for as long as Jon Gray (toe) remains unavailable, and manager Bud Black's decision to move Marquez up to Friday indicates that he's perhaps jumped the struggling Anderson, who owns a 7.71 ERA over six starts, in the rotation pecking order. Marquez faltered in his 2017 debut at Coors Field against the Nationals on April 25, allowing eight runs in four innings, but rebounded in his most recent start on the road April 30 against the Diamondbacks, spinning six shutout innings and striking out eight batters.
