June 30, 2025 2:56 PM : The Red Sox reinstated Mayer (personal) from the bereavement list Monday. Mayer will start at third base and bat sixth in the Red Sox's series opener with the Reds.
Analysis: After being recalled from Triple-A Worcester on Friday when Mayer was deactivated, infielder Nick Sogard will head back to the minors to clear room for Mayer's return to the 26-man active roster. Before stepping away from the team and missing three games while tending to the personal matter, the 22-year-old rookie slashed .208/.262/.429 with four home runs and seven RBI through his first 84 big-league plate appearances. At least until Alex Bregman (quadriceps) returns from the injured list, Mayer is poised to serve as the Red Sox's primary third baseman.
