PITTSBURGH — Pittsburgh Pirates manager Clint Hurdle laughed off what seems to be a renewal of bad blood between his team and the Chicago Cubs.

“Boys being boys,” Hurdle said.

Jason Hammel raised his record to 4-0 and Anthony Rizzo hit two doubles as the Cubs beat the Pirates 7-2 on Monday night.

Home plate umpire Laz Diaz warned both benches after Pirates reliever Kyle Lobstein hit Ben Zobrist with a pitch to lead off the top of the seventh. That came after Hammel hit the last batter he faced, Starling Marte, with a pitch to start the bottom of the sixth.

The teams had a benches-clearing incident in last year’s NL wild card game when Pirates reliever Tony Watson plunked Jake Arrieta, who went on to a pitch a five-hit shutout. Pittsburgh utility infielder Sean Rodriguez was ejected.

Cubs manager Joe Maddon yelled at Lobstein from the dugout then got into a shouting match with Pirates catcher Francisco Cervelli. Maddon and Cervelli became friends in the offseason when Cervelli worked out at a gym owned by Maddon’s wife, Jaye, in Tampa, Fla.

Cervelli said he was standing up for Lobstein.

“He’s my one of my guys,” Cervelli said. “I’ve got to protect my guys if someone starts yelling at them.”

Maddon, meanwhile, said he had no hard feelings toward Cervelli.

“I like him. I really do,” Maddon said. “It’s always fun to vent. We’ve all been there. You have to vent on occasion. The worse thing for your health in the long term is to hold that stuff in.”

Gerrit Cole (2-3) was roughed up for six runs and six hits in 4 2/3 innings after winning his previous two starts. He struck out six but walked four in losing to the Cubs for just the second time in nine regular-season decisions.

“For me, establishing all four corners of the strike zone is key and I didn’t do that,” Cole said. “I was out of sync all night. I just didn’t have it. I definitely have some stuff to work on between starts.”

Jordy Mercer went 3 for 3 with a walk for Pittsburgh and has reached base in 14 straight games but Josh Harrison’s 10-game hitting streak ended as he went 0 for 4. Andrew McCutchen drove in both Pirates’ run with a first-inning homer, his sixth, and a ground out in the fifth.

The Pirates lost their second straight game after winning six in a row.

Hammel’s ERA rose to 1.24 after entering the game with a NL-leading 0.75 mark. He gave up two runs and five hits in five-plus innings with three strikeouts and one walk.

Rizzo hit an RBI double and scored in the third inning as the Cubs went ahead 2-1, then doubled again during a four-run fifth that pushed the lead to 6-1.

The Cubs improved to 18-6.
