Alex Cora, in his first season as big league manager, led the 2018 Red Sox to a title. First baseman Nathaniel Lowe, meanwhile, can draw upon his experience as a member of the 2023 world champion Texas Rangers. “Just don’t overdo it, to be honest with you,” advised Cora before his team took on the Yankees in Game 3 of an AL Wild Card series. You look around the league and every series is coming down to an at-bat here, a play there, a pitch.
