Hendriks (elbow) will make a third rehab appearance Sunday at Double-A Portland, MLB.com reports.

EDGE Analysis

Hendriks opened his rehab assignment a week ago at Triple-A Worcester with an impressive 1-2-3 outing on 12 pitches (10 strikes) , then had less successful results four days later at Portland (third of an inning, one walk, one hit). The report estimates Hendriks could make between six to eight relief appearances while on assignment before being activated.
