Cubs beat Brewers 5-1, stop 5-game losing streak
Arrieta allowed three hits, struck out five, walked one and drove in a run.
Valbuena stopped an 0-for-14 slide with his 12th homer, a solo shot off Kyle Lohse (10-10) in the first. Schierholtz hit a two-run homer in third that landed in the Cubs bullpen in center for a 3-0 lead, and Bogusevic added a pinch- homer off Donovan Hand leading off the ninth.
Lohse gave up three runs and seven hits in five innings. He has allowed 26 homers, tying Washington's Dan Haren for the NL lead.
NOTES: Cubs C Wellington Castro Brewers SS left after the seventh inning with right knee soreness. ... Chicago SS Jean Segura did not play, a day after straining his right hamstring. ... Injured Brewers 1B Corey Hart, eligible for free agency after the World Series, wants to remain with the Brewers. He is making $10 million this year, the final season of a $26.5 million, three-year deal. ''I wouldn't sit there and ask for anything that is outlandish,'' he said. ''I would take a discount to stay here because I think I owe it to them to stay here and be a cheaper player.'' He had surgery on his right knee in late January and missed spring training. ''I've told them I would be very generous to stay here. Nobody wants to play for free, but I've basically sat there and watched all season. That's kind of what we're hoping for, but at the same time, you don't know what's going to happen.'' ... Schierholtz' 21 home runs are 12 more than his previous high of nine with San Francisco in 2011.
