CHICAGO -- Jorge Soler and Kris Bryant hit back-to-back homers to start the fifth inning, and the Chicago Cubs bullpen pitched 6 1/3 innings and held off a late rally to beat Michael Wacha and the St. Louis Cardinals 5-4 on Saturday for their fifth straight win.
Chicago is five games behind NL Central-leading St. Louis, which got a two-run homer from Matt Carpenter in the ninth. The Cubs entered the contest one game behind Pittsburgh for the top NL wild-card spot.
Bryant's drive into the last row of the left-field bleachers gave him 25 homers, tying the Cubs record for a rookie set by Billy Williams in 1961.
