Kris Medlen pitched eight innings of four-hit ball as the Braves beat the Marlins 3-0 on Wednesday.
Atlanta won his start for the 21st straight time.
Medlen lost the first two starts of his career in 2009, but hasn't taken a loss in any of his 26 starts since. With the Braves prevailing in the last 21 of those, they are the first team since the Yankees to have such a streak.
The Yankees won 22 straight times when Whitey Ford started from 1950 through 1953, a span interrupted by his service during the Korean War.
