Marquez (12-11) allowed four runs on six hits and two walks over five innings Monday, striking out four and taking a loss against the Nationals.
Marquez allowed just a single through three scoreless innings to open the game before the Nationals put up a three-run fourth inning. He allowed another run in the fifth and failed to complete six innings for the third straight start. During that span, he's been hammered for 15 runs in 13 innings (10.38 ERA). Marquez will carry a 4.40 ERA into his projected start this weekend in Arizona.
