Martinez (8-9, 3.52 ERA) is coming off a strong start in Kansas City, where he limited the Royals to two runs on seven hits over eight innings to earn his eighth win. He'll face the Braves looking to get to .500 and keep surging St. Louis headed in the right direction.
"You look at that stat sheet and they've got some guys having really good years," Braves manager Brian Snitker said. "Up and down that line. Their whole team is double-digit homers, and they did that last year. It's just a solid, athletic ballclub. That's what they've got. They've got some baseball players and when you have that mix, that's a good thing. Because now they are getting it going and they've been on a run."
Sims (0-2, 5.25 ERA) allowed seven runs on 12 hits in 12 innings in his first two outings, with six strikeouts against two walks.
The 23-year-old right-hander, Atlanta's first-round Draft pick in 2012, was 7-4 with a 3.75 ERA and 132 strikeouts in 115 1/3 innings for Triple-A Gwinnett this season.
