BOSTON — The Boston Red Sox designated veteran first baseman Eric Hosmer for assignment Friday to make room for right-handed pitcher Wyatt Mills, who was acquired from the Kansas City Royals for minor league right-hander Jacob Wallace.
Hosmer, 33, hit .268 with eight home runs and 44 RBI last season, when he was traded to the Red Sox from the San Diego Padres. In a 12-year career with the Royals, Padres and Red Sox, Hosmer has hit .277 with 196 home runs and 879 RBIs.
The 27-year-old Mills was 0-1 with a 4.60 ERA last season with the Seattle Mariners and Kansas City.
Wallace, 24, had a 3.81 ERA in 47 Double-A appearances with Portland.
Also on Friday, the Red Sox traded utility Hoy Park to the Atlanta Braves for a player to be named or cash. Park, 26, hit .216 with two home runs for the Pittsburgh Pirates last season. He was traded to Boston last month for minor league pitcher Inmer Lobo.
