Contreras, Lester lead Cubs past Braves 8-3

CHICAGO (AP) — Willson Contreras homered and had three RBIs, Jon Lester pitched five-hit ball through six innings and the Chicago Cubs beat the Atlanta Braves 8-3 Monday in a chippy matchup of NL division leaders.

Jason Heyward added a solo homer for Chicago, which moved one game ahead of Milwaukee in the NL Central. Lester (7-5) allowed two unearned runs and struck out seven.

The Cubs strung together five straight hits in a five-run fifth inning to break the game open. Kyle Schwarber doubled into the ivy to score Carlos González. Kris Bryant, Anthony Rizzo, Javier Báez and Contreras followed with RBIs.

Tempers flared in the second inning when Contreras homered to right, giving the Cubs a 1-0 lead. Contreras turned to Braves catcher Tyler Flowers after the ball left his bat, and while rounding first base, gestured toward Atlanta’s dugout and thumped his chest.

Contreras and Flowers exchanged words as he returned to the dugout. Heyward escorted Contreras back to the dugout, and Teheran approached the third-base line.

The benches cleared, umpire John Tumpane warned both teams and players congregated on the third-base line. No blows were exchanged.

Báez singled and stole second to lead off the fourth before Contreras made it 2-0. Contreras’ single glanced off shortstop Dansby Swanson’s glove and richocheted into center field as Báez raced home.

Teheran (5-6) was roughed up for the second consecutive start. He allowed six runs in four innings last Tuesday against the Mets.

Nick Markakis drove in two runs with a single in the sixth inning. Swanson hit a towering solo homer in the seventh off Tony Barnette, who made his Cubs debut after being activated from the 60-day injured list.

Atlanta lost for the sixth time in 20 games.

KIMBREL WATCH

Closer Craig Kimbrel will pitch in another game at Triple-A Iowa on Tuesday. Then Cubs management will evaluate his progress. He could be activated later this week.

“There’s certainly a chance that at the very end of this homestand or early on the next road trip we could be seeing him,” president of baseball operations Theo Epstein said.

TRAINER’S ROOM

Braves: Manager Brian Snitker said it’s unclear if rookie RHP Mike Soroka (right forearm) will make his scheduled start Friday against the Mets. Soroka was hit by Washington’s Austin Voth in the third inning of Sunday’s game. Snitker said Soroka had an “extensive forearm workout” Monday and could play long toss Tuesday.

Cubs: RHP Brendan Morrow (offseason elbow surgery) was set to pitch a third bullpen session at the Cubs’ training facility in Mesa, Arizona, on Monday. … RHP Kyle Hendricks (right shoulder inflammation) tossed 15 pitches on Monday and is expected to throw a bullpen session later this week. Epstein said he could return by the All-Star break.

UP NEXT

BRAVES: LHP Max Fried (8-3, 4.03 ERA) takes the mound Tuesday. Fried allowed one hit in six shutout innings against the Cubs on April 4.

CUBS: RHP Adbert Alzolay (1-0, 2.25 ERA) makes his first big-league start Tuesday. He tossed four innings in relief Thursday against the Mets.
