Todd Helton homered and drove in three runs Friday night, leading the Colorado Rockies to a 6-3 victory that ended the Cincinnati Reds' longest winning streak of the season at six games.
Helton had a two-run homer - his first since April 29 - and a run-scoring single off Johnny Cueto (5-2), who gave up a career-high 11 hits in only 4 2-3 innings.
Rookie left-hander Christian Friedrich (2-1) went five innings against an offense that had been on a home run tear - 10 in the last four games. Joey Votto had four hits for the Reds, including a pair of doubles.
Rafael Betancourt pitched a perfect ninth for his eighth save in nine chances.
The struggling Rockies won for only the fifth time in their last 20 games.
