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.

The Cubs pulled 14 games ahead of scuffling St. Louis in the NL Central and improved the best record in the majors to 73-41.

St. Louis outfielder Matt Holliday will have his broken right thumb re-examined early next week, then he and the Cardinals will decide on treatments including surgery or letting the injury heal on its own, according to GM John Mozeliak.

Holliday, who saw the team's hand specialist in Chicago Friday morning, is out indefinitely after getting hit by a pitch in the Cardinals' 4-3, 11-inning loss to the Cubs Thursday night.
