One day after bringing back Craig Kimbrel, perhaps the greatest closer in franchise history, the struggling Atlanta Braves have designated the veteran reliever for assignment. The club recalled left-hander Austin Cox in a corresponding move.

Kimbrel pitched the first five seasons of his career with the Braves, collecting a 1.43 ERA and 186 saves in 294 appearances. He won the 2011 National League Rookie of the Year award and made four All-Star teams during his stint with Atlanta.

The reliever and nine-time All-Star was designated for assignment in an abrupt decision by the Braves on Saturday, which is one outing and one day after Kimbrel was called up from the minors. On Friday night, the 37-year-old made his season debut in Atlanta’s 5-4 loss to the Giants.
