CHICAGO » Joe Maddon wants the Chicago Cubs to prove they can beat the best. Well, how’s this for evidence?

Addison Russell hit a tying single and scored during a three-run rally in the seventh inning, and the Cubs beat the St. Louis Cardinals 5-3 Tuesday to complete a day-night doubleheader sweep.

The Cubs won the opener 7-4 behind a strong start by Jake Arrieta, then came back late in the nightcap. That gave Chicago its first doubleheader sweep against the Cardinals since June 8, 1992, at St. Louis.

“We’re here to win,” Maddon said. “It’s not just to compete.”

Chicago scored three in the seventh to grab a 4-2 lead. Seth Maness got ejected after giving up the tying single and replacement Kevin Siegrist threw away a grounder and allowed two more runs, as the Cubs beat the NL Central leaders for just the fourth time in 12 games.

Travis Wood (5-3) pitched a scoreless seventh. Hector Rondon retired the side in the eighth.

Jason Motte gave up an RBI single to pinch hitter Tony Cruz in the ninth. But he escaped with his fifth save in as many chances after Matt Carpenter fouled out and Jhonny Peralta grounded into a force to end the game.

Hawaii’s Kolten Wong was held out of the second game after banging his head in the opener. The St. Louis second baseman was woozy after he sprawled out to catch a fly by Miguel Montero in shallow right field in the fifth inning. He was slow to get up and was replaced in the seventh.

Down 2-1, Chicago had runners on first and second with one out in the seventh when Russell hit an RBI single just inside the first base line.

As first-base umpire Pat Hoberg called a fair ball, first baseman Mark Reynolds threw his arms up. Maness ran over and was tossed.

“I saw it hit 2 foot foul right in the dirt and it’s really hard to see whereabouts it hit foul again,” Maness said. “I’m really no physics major, but I don’t know how it hits foul and then curves back — but it could — I’m not saying it didn’t.”

In the opener, Arrieta pitched into the seventh inning and also got a career-high two hits.

Anthony Rizzo launched his 16th homer, a two-run drive off Randy Choate during a four-run eighth after St. Louis pulled within one.

Arrieta gave up two runs and seven hits in 62⁄3 innings and improved to 3-0 in his past four starts. He contributed a pair of singles and scored a run after starting the season 1-for-33.
