CHICAGO (AP) The Chicago Cubs are on a roll, and even their depth players are going deep to keep them streaking.
Matt Szczur hit two home runs and the 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 connected 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.
Manager Joe Maddon gave outfielders Dexter Fowler and Jason Heyward a day off following a 4-3, 11-inning win over the Cardinals on Thursday. From left to right, Contreras, Szczur and Soler started in the outfield instead and came through on a muggy afternoon.
Maddon saluted all three, especially Szczur, who shuttled between the Cubs and the minors last season.
''He homers, runs the ball in the outfield, got things going,'' Maddon said. ''I knew he'd be ready to play. He pretty much stirred it up for the entire group.''
''The entire outfield hit four homers today. That not a bad thing,'' he said.
Szczur, who recorded his first multihomer game, and Kris Bryant each had three hits.
''It was awesome to see my name in the lineup when I got to the ballpark today,'' Szczur said. ''Joe has tremendous faith in me and always expects me to produce and I've been able to produce for him.''
The Cubs roughed up Wainwright (9-7) for seven runs and chased him after two innings, tying his shortest outing in 245 career starts.
''I was horrible, Wainwright said. ''My stuff was bad, my delivery was bad, everything was bad. The team deserves more than that.''
Arrieta pitched one-run ball into the sixth inning and gave up four hits overall.
''The story today was our offense was really good,'' Arrieta said. ''I think we know what we're capable of.
''This 11 game winning streak is special, but we want to be playing our best baseball going into October.''
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.
Arrieta delivered a second straight solid start in August after going 0-3 with two no-decisions and a 4.88 ERA in July. The 2015 NL Cy Young winner pitched eight shutout innings at Oakland last Saturday.
Wainwright hasn't won since July 16 and is 0-2 in his last five starts. During that span, he's allowed 21 runs in 25 2/3 innings.
Cardinals slugger Matt Holliday had his broken right thumb examined by the team's hand specialist in Chicago and kidded with teammates in the clubhouse before the game. He's out indefinitely after being hit by a pitch from the Cubs' Mike Montgomery in the 10th inning Thursday night.
Holliday will be re-examined next week. He was replaced in left field by Brandon Moss.
The Cubs jumped on Wainwright early. Line-drive doubles by Bryant and Addison Russell drove in runs in the first to make it 2-0.
Bryant hit another RBI double in the second and Contreras sent his seventh halfway up into the left-center bleachers to make it 7-0.
Szczur and Soler hit solo homers in the sixth off Jerome Williams. Szczur and Baez added two-run shots in the seventh before Gyorko connected in the eighth.
Cardinals: Holliday will decide next week on treatments including surgery or letting the injury heal on its own, according to GM John Mozeliak. Neither Mozeliak or manager Mike Matheny could offer a specific timetable for the slugger's return.
Cubs: RHP Trevor Cahill arrived at the Cubs clubhouse on Friday, but has not been activated from the DL after making six starts at Triple-A Iowa in a rehab stint (right knee tendinitis).
Luke Weaver, a 22-year-old righty and one of the Cardinals' top pitching prospects, will make his major league debut on Saturday against Kyle Hendricks (11-7, 2.17), who is 7-1 with a 1.06 ERA in his last 10 outings. Weaver took Holliday's roster spot and was with the Cardinals on Friday following his recall from Triple-A Memphis, where he made his first start last Monday and threw six strong innings. Previously Weaver was at Double-A Springfield of the Texas League.
