CHICAGO -- In baseball, there's almost always a chance for redemption.
At least that's what Milwaukee shortstop Jeff Bianchi believes after he made up for missed opportunities by driving in a pair of ninth-inning runs Tuesday night. His clutch hit gave the Brewers a come-from-behind, 3-2 victory over the Chicago Cubs and a sweep of the day-night doubleheader.
"That's what's great about this game, to get a chance in the ninth to redeem myself a little bit after a couple of mistakes," he said. "We got a break and scored two runs, and it's a great feeling to get two victories today."
Milwaukee beat Chicago 6-5 in the opener as Jean Segura doubled home Norichika Aoki in the seventh inning with the decisive run.
With two outs and the bases loaded in Game 2, Bianchi lined a hit to left field for the tying and go-ahead runs.
Kevin Gregg, the third Cubs pitcher of the night, gave up singles to Juan Francisco and Segura and then walked Logan Schafer before facing Bianchi.
Gregg (2-3) missed a chance for his 23rd save, instead blowing a save chance for the fourth time this year.
"He didn't get anything going his way tonight," Cubs manager Dale Sveum said.
Brewers right-hander Jim Henderson allowed a single with two outs in the ninth but struck out Junior Lake to end the game and collect his 14th save.
The Cubs entered the inning ahead 2-1 after David DeJesus' seventh-inning double to the wall in right-center scored Cody Ransom and Cole Gillespie. They reached base on back-to-back Brewers errors and advanced on a passed ball by Jonathan Lucroy.
Right-hander Tyler Thornburg got a no-decision despite throwing six scoreless innings in his first career Brewers start. He gave up four hits, struck out six and walked three.
"It was a real nice outing for him," Milwaukee manager Ron Roenicke said. "The first inning he came out throwing strikes, the changeup was great, and his fastball located well and had a lot of life on it. He got us deep where we needed to be."
Burke Badenhop (2-3) got the win after working the seventh and eighth innings.
Jake Arrieta pitched six innings in his Cubs debut, allowing two hits and one run. He walked three and struck out two. Arrieta gave up a fifth-inning solo homer to Francisco that broke a scoreless tie.
"Me and (catcher Dioner) Navarro got on a good page and got off on the right foot and were working well together," Arrieta said. "I could have been more efficient early in the game, but overall it was good."
In Game 1, the Brewers erupted with a four-run seventh inning to overtake the Cubs. Segura doubled home Aoki with a go-ahead run against James Russell (1-3).
Right-handed reliever Rob Wooten (1-0) worked the sixth inning for the win, his first in the major leagues. Henderson pitched a scoreless ninth for his 13th save.
Milwaukee starter Yovani Gallardo escaped without a decision, departing because of left hamstring tightness with the bases loaded and two outs in the fifth. John Axford came in and gave up four straight singles as the Cubs temporarily grabbed a 5-2 lead.
Milwaukee's reply came in the seventh. Starter Carlos Villanueva walked Bianchi and gave up a single to Yuniesky Betancourt before leaving the game with two outs.
Khris Davis greeted Russell with a three-run homer to right to tie the score. Aoki followed with a single, stole second and third and scored the go-ahead run on Segara's double.
Segura and Betancourt each hit their 12th homers of the season, belting solo shots in successive innings for a 2-0 lead.
Villanueva gave up four runs on six hits, struck out six and walked two.
