The Mets had more important matters on their minds Sunday than exorcising the ghosts of Turner Field, which have haunted them for the better part of two decades. In the thick of a skin-tight National League Wild Card race, the Mets simply needed a win. Yoenis Cespedes clubbed a grand slam for his 30th homer and Seth Lugo contributed seven standout innings, moving the Mets a half-game in front of St. Louis for the NL’s second Wild Card spot.
