Boston manager Alex Cora said Kluber will make his next start Sunday in Arizona, Christopher Smith of The Springfield Republican reports.

EDGE Analysis

Kluber lasted just 2.1 innings in a loss to the Padres on Sunday and walked three batters during a four-run first inning. With Garrett Whitlock (elbow) expected to be activated from the 15-day injured list to start this coming Saturday, Boston's rotation will increase to six men. Kluber had been off the radar when it came to potential rotation removals the last few weeks, but it's becoming hard for the Red Sox to continue to hand him starts while he's sporting a 6.26 ERA and 18 walks over 41.2 innings this season.
