June 7, 2025 9:20 AM : Mayer went 1-for-2 with a solo home run in Friday's 9-6 loss to the Yankees.
Analysis: The Red Sox were out of this game early, falling behind 7-0, but Mayer's fifth-inning homer -- a no-doubter -- sparked a rally that turned a blowout into a close game. It was Mayer's first MLB homer, which came one game after he logged is first RBI as a major leaguer.
