(AP) Dioner Navarro hit a tiebreaking single in a three-run eighth inning, and the Chicago Cubs beat Atlanta 3-1 Saturday to keep the Braves on the brink of the NL East championship.
Atlanta's magic number remained at one to clinch its first division title since 2005. Second-place Washington hosted Miami later Saturday.
Starlin Casto singled off Kris Medlen with one out in the eighth, pinch-hitter Donnie Murphy singled against Scott Downs (2-1) and Anthony Rizzo hit a tying double down the left-field line.
Navarro singled in the go-ahead run against David Carpenter, and Nate Schierholtz added a sacrifice fly.
Carlos Villanueva (7-8) got three outs in the eighth, and Pedro Strop finished for his first save in four chances.
Atlanta went ahead in the fourth when Freeman walked and scored on Gattis' single.
Medlen, 4-0 with an 0.98 ERA in his previous four starts, allowed one run and six hits in 7 1-3 innings. Wood gave up one run, five hits and four walks in seven innings with seven strikeouts.
NOTES: Braves manager Fredi Gonzalez said OF Jason Heyward "was feeling great," a day after Heyward returned from the disabled list. Heyward was not in the lineup on Saturday after going 0 for 2 with a walk in his first appearance since breaking his jaw on Aug. 21 because of a broken jaw. ... The Cubs unveiled a logo to celebrate the 100th anniversary of Wrigley Field in 2014. It shows the ballpark's familiar marquee and facade with "100 years 1914-2014." The logo, which will be featured as a patch on the team's home uniform next season, was submitted by Brandon Ort of New Bremen, Ohio, as part of a fan contest before the season. ... RHP Julio Teheran (12-8, 3.14 ERA) starts Sunday for Atlanta, with RHP Edwin Jackson (8-16, 4.75) pitching for Chicago.
