Marquez (14-11) allowed four runs (two earned) on five hits and two walks while striking out nine over 4.2 innings and taking the loss Monday against the Dodgers.
Marquez surrendered a two-run blast in the fourth inning followed by another two-run homer in the fifth before exiting in a 4-0 ballgame. The 23-year-old failed to lead his team to a division title, so the Rockies will take the field Tuesday in Chicago for the wild-card game. If Colorado can beat the Cubs, Marquez figures to pitch on Sunday against the Brewers.
