In his final appearance in a Red Sox uniform, he relieved Clay Buchholz in Game 6 of the ALCS.

Morales was replaced by Brandon Workman who ended the inning without further damage. The Sox won the game when Shane Victorino hit a 7th inning grand slam. Morales did not pitch in the World Series as the Red Sox won the championship over the St. Louis Cardinals. He was traded by the Red Sox before the end of the year.
After being primarily a relief pitcher for the Red Sox in his previous three years, Morales found his way back into a starting role to begin the 2014 season with the Rockies; he made his season debut on April 3 as the team's fourth starter, giving up 3 earned runs and 8 hits in 5+1⁄3 innings in a no decision against the Miami Marlins.[4][5]
