The Boston Red Sox placed second baseman Vaughn Grissom and infielder/outfielder Romy Gonzalez on the 10-day injured list on Sunday because of hamstring strains.
In corresponding moves, the Red Sox selected infielder/outfielder Jamie Westbrook and recalled infielder/outfielder Bobby Dalbec from Triple-A Worcester.
Grissom missed the first 32 games of the season because of a left hamstring strain in spring training. He injured his right hamstring running out a grounder in the bottom of the second inning in the 6-3 home win over the Detroit Tigers on Saturday.
