Jorge Soler hit a three-run homer during a five-run first inning, Jon Lester pitched into the seventh and the Chicago Cubs beat the Milwaukee Brewers 6-1 on Wednesday night for their 17th win in 20 games.
Soler's shot capped the inning after RBI singles by Ben Zobrist and Addison Russell.
Lester (13-4) got his fourth straight win, giving up one run and three hits in 6 2/3 innings while striking out seven. He hasn't lost since July 3.
Brewers starter Jimmy Nelson (6-13) walked leadoff batter Dexter Fowler then hit Kris Bryant with a pitch to set the table in the first.
Soler's homer on a 2-2 pitch was a convincing smash that landed just under the videoboard atop of the left-center field stands.
Nelson is 1-10 over his last 14 starts.
