Atlanta optioned Ritchie to Triple-A Gwinnett on Sunday.
Ritchie's stay with Atlanta lasted just one day, with the 23-year-old righty working out of the bullpen in Saturday's 14-3 win over the Mets and striking out four over three scoreless innings en route to collecting his first career save. Atlanta called up Carlos Carrasco from Triple-A in a corresponding move and will have him join the bullpen as a replacement for Ritchie, who will slot back into the rotation at Gwinnett.
