Montgomery will remain in a starting role for the time being as the Cubs go with a six-man rotation, MLB.com's Carrie Muskat reports.

EDGE Analysis

Though John Lackey (shoulder) returned from the disabled list Sunday and turned in an effective outing against the Giants, the Cubs will attempt to limit the usage of their starting pitchers down the stretch in preparation for the postseason. Montgomery's presence in the rotation will create an extra built-in day of rest for the team's other starters, but the left-hander might be worth a look in deeper mixed leagues while he holds down a starting gig. In 24.2 innings as a starter this season, Montgomery has produced a 4.01 ERA and 1.34 WHIP.
