CHICAGO -- Daniel Murphy homered for a record-tying fifth straight game in the postseason, sending Jacob deGrom and the New York Mets over the Chicago Cubs 5-2 on Tuesday night for a 3-0 lead in the National League Championship Series.

Yoenis Cespedes and David Wright each had three hits for the Mets. Cespedes scored the go-ahead run on a two-out wild pitch by Trevor Cahill on a strikeout of Michael Conforto in the sixth inning.

Murphy tied the homer streak mark set by Carlos Beltran in 2004.
