The best-of-five series now heads to Wrigley Field for Games 3 and 4 Monday and Tuesday. The Cubs were the only team to win a postseason game on the road this year.
Willson Contreras hit a solo homer and Anthony Rizzo added a two-run shot for the Cubs to give starter Jon Lester a 3-1 lead. But Chicago's bullpen uncharacteristically faltered. With the Nats trailing, 3-1, with one out and one on in the eighth, Harper connected against Carl Edwards Jr., who had not given up a hit since Sept.
