CINCINNATI -- Bronson Arroyo limited the NL's most prolific offense to four singles in eight innings, and Jay Bruce had a two-run homer among his three hits, leading the Cincinnati Reds to a 3-0 victory over the Colorado Rockies on Monday night.

The Reds have three shutouts in their last four games. They've blanked six of their last 21 opponents, tying them for the league lead with nine shutouts this season.

Arroyo (6-5) allowed only one runner to reach second base. Aroldis Chapman got his 15th save in 17 chances.

Bruce scored on Todd Frazier's single in the fourth inning off Tyler Chatwood (3-1). He hit his ninth homer off left-hander Josh Outman in the eighth.

Colorado fell to 1-6 against Cincinnati over the last two seasons.
