Marquez has a good shot to earn a spot in the Rockies rotation.
With Chris Rusin (oblique) and Chad Bettis (illness) on the shelf, the Rockies are now tasked with filling two rotation spots rather than just one. This leaves Marquez in a good position to pick up one of those spots given his solid debut last season. However, the 22-year-old is experiencing some struggles this spring, as he holds a lofty 7.94 ERA and 2.12 WHIP in three appearances, so he'll need to shore up those issues if he wants to hold off Jeff Hoffman, Antonio Senzatela and Kyle Freeland for the final two rotation spots.
