Red Sox's Vaughn Grissom: Placed on IL

The Red Sox placed Grissom (hamstring) on the 10-day injured list Thursday.

The transaction is retroactive to Monday, but Grissom won't be ready to come off the IL once his 10 days are up. The 23-year-old infielder will need more time to build back up after missing most of spring training due to the right hamstring strain, as well as a minor groin injury that delayed his recovery. According to MLB.com, manager Alex Cora said Sunday that Grissom is about 7-to-10 days away from seeing game action in any form, so he could be ready to begin a rehab assignment at some point next week.
