The tenure of Chris Martin with the Braves has been largely good with a couple notable exceptions. Last year in the playoffs, Martin was injured early in the series against the Cardinals while warming up and a lot of people think that if he had been healthy for that series, the Braves would have moved on to the next round. Such is life.
Martin had himself quite the 2019 season as a reliever. With the Rangers and Braves last year, he posted a 1.1 fWAR season with a 2.25 ERA while striking out 10.51 batters per nine innings.
