Michael Busch notched his first career multi-home run game, fellow rookie Pete Crow-Armstrong also went deep and the Chicago Cubs beat the Colorado Rockies 6-2 in Denver on Sunday.Busch finished with three hits and three RBIs, while both Nico Hoerner and Ian Happ had two hits for Chicago.Kyle Hendricks (4-11) allowed one run on two hits in six innings to earn his first victory for the Cubs since July 31. The right-hander walked three and struck out seven. Hendricks was 0-2 over his last six starts but helped Chicago (76-73) snap a three-game losing streak and keep its slim National League wild-card hopes alive.Jacob Stallings homered for Colorado (57-93), which managed just four hits on the day. The Rockies had their three-game winning streak snapped.Colorado starter Cal Quantrill, activated from the 15-day injured list (right triceps inflammation) before the game, struggled with his control, and it cost him in the third inning. Quantrill issued a pair of one-out walks to Cody Bellinger and Isaac Paredes, and Busch followed with an RBI single to put the Cubs up 1-0.Paredes came home on Hoerner’s ensuing infield single to make it 2-0. Hoerner stole second before Quantrill issued his sixth walk of the game, which put Crow-Armstrong on first to load the bases.Jeff Criswell came on and struck out Miguel Amaya and escaped more damage when Brenton Doyle made a leaping catch of Happ’s drive to the wall in center to end the inning.
