Righty Drew Rasmussen (7-5, 2.82 ERA) will start for Tampa. The Red Sox reinstated Hunter Dobbins from the IL after he missed 18 games with a right elbow strain. Boston optioned utility player David Hamilton and righty reliever Isaiah Campbell to Triple-A Worcester to clear roster spots for Bregman and Dobbins.

Bregman's contract, relationship with his teammates and the Red Sox's current playoff position make it very unlikely he'll be dealt in July.

The Red Sox sent David Hamilton down to Triple A to clear a roster spot for Bregman, who returned at third base. Romy Gonzalez and Ceddanne Rafaela will mix in at second with Mayer.
