BALTIMORE (AP) — Colorado hit four home runs, including a tiebreaking, two-run shot by Wilin Rosario in the seventh inning, and the Rockies beat the Orioles 6-3 Friday night to extend Baltimore’s losing streak to four games.

Charlie Culberson, Charlie Blackmon and Todd Helton also homered for the Rockies, who have won six of seven. It was Culberson’s first major league home run in 55 at-bats.

Juan Nicasio (7-6) allowed two runs, four hits and four walks over six innings to earn his first win in five starts since July 20. The right-hander yielded 15 runs over 14 innings in his previous three outings and was 0-3 with a 7.79 ERA in four interleague starts this season.

Wei-Yin Chen (6-6) retired 12 of his first 13 batters but couldn’t get out of the seventh inning.
