MLB rosters expand by two on Monday, but the Boston Red Sox reportedly have no imminent plans to bring back Kristian Campbell. The Red Sox are not promoting Campbell as a Sept. 1 call-up, according to MassLive’s Christopher Smith. Campbell made Boston’s Opening Day roster and signed an eight-year, $60 million contract a week into his MLB career. The top prospect sprinted out of the gate as an American League Rookie of the Year favorite by batting .301/.407/.495 through April.
