To take Hermida’s spot on the roster, the Red Sox promoted 22-year-old prospect Ryan Kalish from Triple-A Pawtucket and immediately inserted him into today’s lineup, hitting eighth. Hermida had been penciled into the original lineup.
Kalish, who will wear No. 55, 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.
It was immediately unclear what the Red Sox got from the Giants in return for Ramirez, who was 0-3 with a 4.46 ERA in 44 appearances this season. To take his spot, the Red Sox have promoted reliever Dustin Richardson.
Richardson’s stint in Boston could be a short one, as the team announced earlier in the afternoon their plan to convert lefty prospect Felix Doubront from a starter to a reliever. The team also could call up converted starter Michael Bowden in the Pawtucket bullpen.
Hermida, who was acquired from Florida via trade over the winter, struggled during his short time in Boston. He missed significant time with a rib injury and hit only .203 with 5 homers and 27 RBIs in limited time. The Red Sox now have 10 days to either trade or release him.
Richardson was promoted to Boston on June 12 and appeared in 13 games for Boston with a 2.57 ERA. He was optioned back to Pawtucket on July 21.
