CHICAGO -- Right-hander Bronson Arroyo allowed just two base runners through seven shutout innings and Todd Frazier went 2-for-4 with a homer to lead the Cincinnati Reds to a 5-0 victory over the Chicago Cubs on Tuesday afternoon.
The win completed a three-game Cincinnati series sweep and Chicago was shut out for the fourth time in its last five home games dating to Aug. 3.
Arroyo (11-9) allowed singles to David DeJesus and Darnell McDonald while walking none and striking out seven.
Reds right-handed reliever Alfredo Simon worked a perfect eighth and Jonathan Broxton allowed one base runner -- a hit batter -- in a scoreless ninth.
The victory was the Reds' fourth straight and sixth in their last seven games. The Cubs have lost four in a row.
Frazier gave Cincinnati a 1-0 lead in the first inning with a first-pitch home run to left off Cubs starter Chris Rusin. Frazier's 11th home run of the season cleared the left field fence and landed on Wavelend Avenue.
The Reds added a run in the fifth as catcher Ryan Hanigan doubled home Zack Cozart from first base with one out. Cozart collected an RBI double off Cubs reliever Carlos Villanueva in the seventh, scoring Jay Bruce from second for a 3-0 Reds lead.
The Reds added two in the eight with no outs. Frazier doubled home Chris Heisey and then scored on Joey Votto's two-base hit down the first base line.
Rusin (2-2) worked six innings and allowed two runs and three hits, struck out three and walked one.
