How it happened: The Cubs' offense continues to sputter. They had three baserunners through eight innings, none of them advancing beyond first base. Former Cincinnati pitcher Travis Wood was seeking his sixth win of the season, and he held the Reds hitless until a Cesar Izturis infield single to deep shortstop in the fifth. Todd Frazier gave the Reds the lead in the seventh inning with a long home run to left center field. Wood was strong, but Mike Leake was stronger, going eight innings before yielding to Aroldis Chapman in the ninth.
Outfielder Nate Schierholtz hit a solo home run off Leake for the Cubs' only run.
What it means: The Cubs are a woeful 7-21 in Central Division play. That is the worst intradivision record in baseball. The Reds have won 12 in a row at Wrigley Field dating back to 2012. Wood threw his 12th quality start in 13 outings this season.
Outside the box: The team put Zach Putnam on the DL with right elbow soreness. Brooks Raley was selected from Triple-A Iowa. Raley was 5-4 with a 4.92 ERA in the minor leagues. The Cubs have lost 20 games in which they had a lead.
