Teheran, who came in with 18 straight scoreless innings against Colorado, allowed just five Rockies to reach base over 7 1/3 innings in a 5-2 Braves victory Friday night.
Teheran won his first start at the Braves' new ballpark, beating San Diego on April 14, but then went winless in his next 12 Atlanta starts while posting a 7.36 ERA and setting a Braves record for consecutive home losses.
Rockies right-hander Chad Bettis pitched seven scoreless innings against the Braves at Colorado on Aug. 14 in his return from testicular cancer, matching Teheran's outing in that game.
Bettis (0-1) was victimized by early homers from Kemp and Suzuki this time, allowing five runs and six hits over five innings.
Charlie Blackmon, who leads the National League with a .337 average, drove in the Rockies' first run, but had to leave in the eighth inning after tweaking his left leg on a swing.
Mark Reynolds connected in the seventh inning off Teheran for his 27th homer.
The loss was the 12th in the past 17 games for the Rockies, who are 7-24 on the road after a 24-10 start away from Colorado.
Kemp was 3-for-4 with a double in addition to his homer, and Ozzie Albies was 2-for-2 with a double and two walks.
Arodys Vizcaino pitched the ninth inning for his eighth save in 10 chances, allowing one hit and striking out one.
Kemp's two-run blast in the first inning was his 15th homer of the season and first since July 25 in Arizona.
Suzuki, also connecting on a first pitch, belted his career-best 15th of the season and 10th since the start of July to lead off a three-run second inning.
The Rockies had gone 20 consecutive innings without scoring against Teheran until Blackmon delivered an RBI single in the third.
