Hermida designated for assignment

BOSTON -- The Red Sox made at least one move on trade deadline day, designating outfielder Jeremy Hermida for assignment and promoting outfield prospect Ryan Kalish from Triple-A Pawtucket.

The 22-year-old Kalish, who will wear No. 55, was immediately inserted into the starting lineup, batting eighth. Hermida had been penciled into the lineup originally.

Kalish was hitting .294 in 37 games for Triple-A Pawtucket, with 5 homers, 18 RBIs, 22 runs scored and 12 stolen bases. Prior to being promoted earlier this season, he hit .293 with 8 homers, 29 RBIs, 35 runs scored and 13 stolen bases in 41 games for Double-A Portland.

A source also said reliever Dustin Richardson was on his way to Fenway Park, but it was unclear whether he would be activated.
