Rookie Elehuris Montero homered twice and drove in five runs to back the solid pitching of José Ureña, and the Colorado Rockies beat the San Francisco Giants 7-4 on Friday night to snap a five-game losing streak. Connor Joe also homered and Wynton Bernard and José Iglesias hit successive doubles to ignite a four-run fifth inning by Colorado, which sent the Giants to their third straight loss. Ureña (2-4), who joined the Rockies in May on a minor league contract after being designated for assignment by the Milwaukee Brewers, went 6 2/3 innings and allowed three hits, two of them to Joc Pederson.
