The ghosts of the 2015 World Series and the Giants celebrated at Citi Field Wednesday night. Closer Jeurys Familia, who blew three saves in the Fall Classic last year, gave up a three-run home run in the top of the ninth to Conor Gillaspie as the Giants beat the Mets, 3-0, at Citi Field in the National League wild card game. The homer by the Giant’s third baseman and a complete-game, four-hit shutout by Giants ace Madison Bumgarner, advanced them to the NL Division Series against the Cubs beginning Friday. Bumgarner has now pitched 23 straight scoreless innings in postseason elimination games. Familia’s pitch, a sinker inside that missed its spot, ended an unlikely run for the Mets, spoiling a brilliant start by Noah Syndergaard and bringing back flashbacks of Familia’s struggles last postseason.Syndergaard pitched seven shutout innings, scattering two hits and striking out a postseason career-high 11 batters. He became the first Mets pitcher to start a playoff game with five no-hit innings since Jerry Koosman in Game 2 of the 1969 World Series. “It stings a little bit right now. It still hasn’t sunk in yet that the season’s over with,” Syndergaard said, “but I couldn’t be more proud of this group of guys, after everything we’ve been through.” The Mets had overcome season-ending injuries to three of their starting five pitchers. They lost David Wright and Neil Walker for the season and Lucas Duda for most of it. Yoenis Cespedes, Asdrubal Cabrera and Jose Reyes all spent time on the disabled list.
