Anderson will make his next start Saturday against the Diamondbacks, Nick Groke of The Denver Post reports.
The Rockies initially tabbed the struggling Anderson for the series opener, but he'll now move back a day after manager Bud Black opted to give rookie German Marquez, who tossed six shutout innings in his last start against the Diamondbacks over the weekend, the nod Friday. Anderson hasn't been able to carry over the success he enjoyed in his rookie season into 2017, as the lefty has struggled in particular with keeping the ball in the yard. He's allowed at least one homer in all six of his starts, and has seen his strikeout and walk rates trend in the wrong direction as well.
