Steve Pearce, the career journeyman who broke loose to become the unlikely MVP of the 2018 World Series, says he's done playing after an injury-plagued season for the Boston Red Sox. Pearce made the announcement Monday night on WEEI while the Boston radio station aired a replay of the 2018 World Series opener between the Red Sox and Los Angeles Dodgers. "What Steve did for us in '18 was pretty incredible," Red Sox manager Ron Roenicke said Tuesday on a conference call.
