Red Sox's Vaughn Grissom: Activation this weekend unlikely

Red Sox manager Alex Cora said Thursday that Grissom (hamstring) is getting close to being activated from the 10-day injured list but is unlikely to be reinstated this weekend, Chris Cotillo of The Springfield Republican reports.

Grissom has played six rehab games with Triple-A Worcester, starting at second base for the last three of them. The Red Sox have an off day Monday before beginning a series with the Giants at home Tuesday, and that could be the day the club is targeting for Grissom's season and team debut.
