Whitley was optioned to Triple-A Gwinnett on Monday.
Whitley was removed from the roster to make room for Mike Soroka, who is set to make his major-league debut Tuesday. Whitley pitched just one inning in his brief stint with the Braves, allowing two runs. He'll likely shuttle back and forth between Atlanta and Gwinnett throughout the year, providing depth in the bullpen whenever the big club needs a fresh arm.
