Johan Camargo hit a go-ahead, three-run double as the Atlanta Braves took advantage of five walks by Cubs relievers in the eighth inning to beat Chicago 6-4 on Wednesday night.

Willson Contreras gave Chicago the lead with a long, two-run homer in the sixth. But the Cubs’ much-criticized bullpen went wild in the eighth and blew a 4-2 lead — it was Chicago’s third blown save this season and third loss by a relief pitcher in five games.

Steve Cishek (0-1) walked Atlanta’s first three batters in the eighth before manager Joe Maddon brought in left-hander Randy Rosario. After taking a ball, Camargo lined the three-run double over Albert Almora Jr. in center field for a 5-4 lead. Camargo scored from third on Dansby Swanson’s sacrifice fly for a two-run lead.

Luke Jackson (1-0) pitched a scoreless eighth for Atlanta. Arodys Vizcaino walked Anthony Rizzo with one out in the ninth before striking out Javier Baez and Kyle Schwarber for his first save.

Swanson and Albies hit third-inning homers off Jon Lester, who allowed two runs on six hits in six innings.

Contreras connected off Jonny Venters, giving the Cubs a 3-2 lead. The ball traveled 452 feet, according to Statcast, before landing on the second tier of landscaping behind the centerfield wall.

Braves starter Julio Teheran allowed one run on six hits and three walks in five innings and left with a 2-1 lead. Venters didn’t record an out before blowing the lead. Venters walked Schwarber before Contreras delivered the go-ahead homer.

The Cubs, who committed six errors in an 8-0 loss to the Braves on Monday night, had another poor game on defense. Albies led off the game with a single up the middle that bounced past Jason Heyward in center field for a two-base error. Lester pitched around the error.

Lester reached base three times, on a second-inning single that drove in Contreras and two walks.
