The Boston Red Sox may be getting a major upgrade at first base this winter. FanRag Sports’ Jon Heyman reported Thursday that “there is an expectation” the Red Sox could pursue former All-Star slugger Eric Hosmer in free agency. The 28-year-old Hosmer is coming off perhaps his best season yet — he appeared in all 162 games for the Kansas City Royals, batting .318/.385/.498 with 25 home runs and 94 RBIs.
