The Colorado Rockies are bottoming out and this could lead them to do a wholesale purge of trade assets at the deadline. Márquez was signed by the Tampa Bay Rays as an international free agent out of Venezuela in 2011. Five years later, he was included in a trade with Colorado. The Rockies received Márquez and left-handed pitcher Jake McGee in return for left fielder Corey Dickerson and third baseman Kevin Padlo.
