National League game: Mets at Cubs, 5:00PM PT, TV: TBS

This one is also an elimination game: the Mets are one win away from going on the World Series. If the Cubs are to make the prediction in the movie “Back to the Future” come true, they have to win the next four games. The Mets send out lefty Steven Matz, making his first appearance in the NLCS after giving up three runs in five innings against the Dodgers in the NLDS. He’ll be opposed by Jason Hammel, also appearing for the first time in the NLCS after a short (four runs in three innings) outing against the Cardinals in the NLDS.
