Ryan McMahon’s offensive surge continued Friday night. The third baseman belted his fifth home run in eight games and hit a go-ahead RBI single to help the Rockies snap a four-game losing streak by beating Kansas City, 7-2, on the road at Kauffman Stadium. With the game tied at two in the eighth after left fielder Jurickson Profar’s fielder’s choice, McMahon stepped into the batter’s box with runners at the corners and one out.
