Lucas Giolito Injury: Slated for additional rehab starts

Giolito (hamstring) will make his fourth minor-league rehab start Sunday with Double-A Portland and is expected to require an additional rehab start after that before being activated from the 15-day injured list, Christopher Smith of MassLive.com reports.

The right-hander began his rehab stint by allowing just one run over 5.2 frames across his first two starts, but he was tagged for three runs over two innings his last time out Tuesday. He's struggled with his control so far, logging a 9:7 K:BB across his 7.2 frames. Boston is expected to get Brayan Bello (shoulder) back from the IL on Tuesday, making Giolito's return slightly less urgent, though Kutter Crawford (knee) and Richard Fitts (pectoral) also remain on the shelf and with unclear timelines to return.
