Whitlock (pectoral) won't be reinstated from the 10-day injured list Saturday, Chris Cotillo of The Springfield Republican reports.

EDGE Analysis

Whitlock threw a bullpen session Friday, but he won't rejoin the active roster Saturday. Manager Alex Cora isn't yet sure whether the right-hander will be able to return Sunday, but it wouldn't be surprising to see him available for the postseason if the Red Sox secure a wild-card spot.
