Being the senior vice president of fan services and entertainment at the renowned Boston Red Sox has its perks. But the owner of that title, Sarah McKenna, explains how none of it matters if you lose sight of what your role means. Fan Services: everything is for the fans who are here to be served. Entertainment: fans have to be pleased night after night,   good team or bad, rain or shine, happy times (player retirements and military family reunions) or bad times (the 2013 Boston bombings or national unrest).   Meet Sarah McKenna, the game face exec who loves her fans as much as they love her team.
