After signing a minor-league deal with the Braves last November, the 27-year-old Brigham made his big-league debut in 2015 and struggled, allowing 16 runs in 16 2/3 innings. He spent a larger portion of the season with Double-A Mississippi and Triple-A Gwinnett and fared better, however, combining for a 3.46 ERA, 6.8 K/9 and 2.1 BB/9 in 91 innings in the minors. In June, he also took a perfect game into the ninth inning with Mississippi.
The 29-year-old Kohn pitched six outings with the Braves early in the year but suffered a shoulder strain in May and missed much of the rest of the season before briefly returning to minor-league action this month. The reliever has struggled with his control in a big-league career that spans parts of five seasons, posting a 3.52 ERA, 8.7 K/9 and 6.2 BB/9 in 115 career innings.
