CHICAGO (AP) Matt Szczur hit two home runs and the Chicago Cubs won their 11th straight game, backing Jake Arrieta and battering Adam Wainwright to rout the St. Louis Cardinals 13-2 Friday.

Willson Contreras launched a three-run shot to cap a five-run second inning, and Javier Baez and Jorge Soler also went deep to make things easy for Arrieta (14-5).

The Cubs' winning streak is their longest since a 12-game run in 2001. They pulled 14 games ahead of scuffling St. Louis in the NL Central and improved the best record in the majors to 73-41.

Szczur, who recorded his first multihomer game, and Kris Bryant each had three hits. The Cubs roughed up Wainwright (9-7) for seven runs and chased him after two innings, tying his shortest outing in 245 career starts.

Arrieta pitched one-run ball into the sixth inning and gave up four hits overall.

Stephen Piscotty and Jedd Gyorko homered for the Cardinals, who remain in a tight race for the second NL wild card despite dropping six of their last nine.
