Beginning assignment Friday
Contreras (hamstring) will begin a rehab assignment at Double-A Portland on Friday, Tim Healey of The Boston Globe reports.
Analysis
Contreras took batting practice on the field before Tuesday's game against the Angels as the latest step in his recovery from a left hamstring strain. He'd been a candidate to return from the injured list for Friday's series opener against the Royals, but the Sox will instead have him play in a few tune-up games before adding him back to the active roster.

Takes on-field batting practice
Contreras (hamstring) took batting practice on the field at Fenway Park on Tuesday, Tim Healey of The Boston Globe reports.
Analysis
Contreras is also expected to do some running on the field during Boston's series against the Angels that runs through Wednesday. It hasn't been determined yet whether Contreras needs a short rehab assignment before returning to the active roster. If he skips one, he could be activated as soon as Friday. Contreras has been out since late August with a left hamstring strain.

Could be back as soon as Friday
Red Sox interim manager Chad Tracy said Monday that Contreras (hamstring) will resume running during the team's current series against the Angels and could be activated from the 10-day injured list as soon as Friday's series opener versus the Royals, Marcus Grunfeld of ElEmergente.com reports.
Analysis
Tracy also added that Contreras could go out on a short rehab assignment before returning to the active roster, but he plans to speak with the first baseman about that possibility later this week. Contreras landed on the IL one week ago because of a left hamstring strain. Mickey Gasper has been filling in at first base for the Red Sox.
