The Boston Red Sox have placed starter Brayan Bello on the 15-day injured list, retroactive to April 21, due to a right lat strain. Bello, who tossed six shutout innings and struck out seven Friday night in Pittsburgh, was supposed to start Thursday’s series finale against the Cleveland Guardians. Instead, he’ll be out at least through May 7, which is the first day he can return from the IL. The Red Sox are now missing three-fifths of their starting rotation, with Bello joining Nick Pivetta (flexor strain) and Garrett Whitlock (oblique strain) on the injured list.
