Working a third straight game, Aroldis Chapman gave up a hit and a walk with one out but struck out the side for the win.
Called up from Triple-A Albuquerque earlier in the day to replace Jorge De La Rosa, who had an cut on his finger, lefty Chris Rusin delivered seven strong innings of work for the Rockies. Rusin had a 6.29 ERA in the Minors, but he gave up one run and four hits with four walks and five strikeouts vs. the Reds.
Also not getting a decision despite a nice effort was Reds rookie Michael Lorenzen, who was making his first start since May 10.
