1. Mets Win The NL Pennant

Seriously, it happened. The New York Mets actually won the National League pennant. They swept the World Series favored Chicago Cubs who had just upended the top seeded St. Louis Cardinals. The Mets, led by the aforementioned Daniel Murphy, were comfortably the best team in the series, and finished off the sweep with an 8-3 victory at Wrigley Field.

This signified the culmination of a long and painful waiting period for Mets fans. From the heartbreak of 2006, to the collapse of 2007, to the losing years of 2008-2014, the Mets were the second best team in New York for a long time. However, fueled by a youthful pitching staff, a rejuvinated offense, and several standout performers, the Mets managed to snake their way past the Dodgers and Cubs, and return to the World Series for the first time since 2000. They were downed by the Kansas City Royals in five games, but the fact that they made it to the World Series signifies the biggest moment in New York Sports in 2015.
