The Boston Red Sox are calling up infielder Marcelo Mayer, the No. 6 prospect in baseball and a central part of their future who they hope can play a role in their push for a postseason berth this year, sources told ESPN.
Mayer, 22, who has excelled at shortstop as he ascended through the Red Sox\'s farm system after they took him with the fourth overall pick in the 2021 draft, is likely to get playing time with All-Star third baseman Alex Bregman expected to land on the injured list after leaving Friday\'s game with right quadriceps tightness.
