Jenkins, acquired in the November 2014 trade that sent Jason Heyward to St. Louis, began the game with a 6.43 ERA and 26 baserunners allowed in his first three career starts, a span of 14 innings.
Jenkins (1-2) did a lot better against the Phillies, allowing one unearned run on four hits and four walks. He struck out four.
Pitching exclusively from the stretch, Jenkins struggled with his command in the fourth, walking two and loading the bases with two outs, but Odubel Herrera swung at the first pitch and popped up.
Jim Johnson, the fourth Atlanta pitcher, earned his fifth save in eight chances.
Vince Velasquez (8-3) gave up seven hits, two runs, two walks and struck out five in six innings.
