Albert Almora Jr. drove in the go-ahead run with a ninth-inning double, Dexter Fowler had two hits and the Chicago Cubs defeated the Washington Nationals 4-3 on Tuesday night.
Addison Russell led off the ninth with a walk from Sammy Solis (1-2) and was sacrificed to second before Almora, who entered the game in the eighth inning, lined a shot to left center.
Jason Heyward provided a two-run single for Chicago, which evened the three-game series between division leaders.
Washington, which had won four straight, tied it in the eighth on a sacrifice fly by Anthony Rendon off closer Hector Rondon.
