The Rockies will send Jhoulys Chacin to the mound on Sunday as Colorado looks to take the rubber match of this three-game weekend set with the Chicago Cubs. Chacin struggled earlier in the year before hitting the disabled list with right shoulder inflammation, but looked good on Tuesday in his return, allowing just one run and four hits in six innings of work.

Here is Sunday's Colorado lineup, via MLB.com's Rockies reporter, Thomas Harding:

#Rockies vs. #Cubs: Blackmon9, LeMahieu4, Pacheco3, Gonzalez7, Rosario3, Colvin8, Nelson5, Herrera6, Chacin1.
