Manager Alex Cora said Sunday "there's a good chance" Whitlock (elbow) will be activated from the 15-day injured list to start Saturday against the Diamondbacks, Christopher Smith of The Springfield Republican reports.

EDGE Analysis

The 26-year-old made his second rehab start with Triple-A Worcester on Sunday and threw 79 pitches across 4.2 scoreless frames, lining him up to rejoin the big-league rotation next weekend in Arizona. Whitlock is nearly built up to a full starter's workload, so any limitations in his first start back with the Red Sox should be minor.
