Valentine was officially introduced as the new manager of the Boston Red Sox on Thursday after agreeing to a two-year deal. He replaced Terry Francona, who led the Red Sox to two World Series championships but left Fenway Park in September after the team missed the playoffs following a dramatic late-season collapse.
