Mayer went 1-for-3 with a two-run double during Boston's 4-3 loss to Tampa Bay on Tuesday.
Mayer brought the Red Sox to within one run after his groundball in the eighth inning ricocheted off first base, resulting in a double that brought home both Caleb Durbin and Isiah Kiner-Falefa. Mayer has had an up-and-down season at the plate but has gone 2-for-5 with a home run and three RBI through the first two games of the series against the Rays.
