NEW YORK -- It's win or go home. There's no third chance. The Mets and Giants overcame some inconsistent moments along the way to the postseason, and now they get a second chance to make postseason memories. It is a one-game matchup of National League Wild Cards at Citi Field on Wednesday (ESPN, 8 p.m. ET/5 p.m. PT) to decide who will advance to the NL Division Series against the Cubs, which begins on Friday night.
