While his Boston teammates are making the much-ballyhooed trip to London this weekend, Mitch Moreland is staying stateside. The Mississippi State alum remains on the injured list, recuperating from a quadriceps injury. He has been sidelined for all but one day since May 26. Moreland took live batting practice at Fenway Park this week and reportedly will head out on a rehab assignment soon. The Red Sox, the defending world champs, could certainly use Moreland’s bat (not to mention his glove at first base) as they try to chase down the New York Yankees in the American League East. When he initially went on the injured list with a back injury in late May, Moreland was leading the Red Sox in home runs with 13. He was activated on June 7, went 0-for-2 against Tampa Bay, then went back on the IL the next day with the quad injury. He is batting .225 (slugging .543) with 34 RBIs in 47 games. An All-Star in 2018, the injury woes have assured that Moreland won’t be going to Cleveland on July 9. P.S. Former Ole Miss standout Mike Mayers, on the IL (shoulder) since mid-April for St. Louis, has begun a rehab assignment at Triple-A Memphis. Mayers, in his fourth big league tour, had a 5.40 ERA in eight appearances for the Cardinals this season.
