Atlanta will recall Ritchie from Triple-A Gwinnett to start Wednesday's game against the Cubs, Jesus Cano of The Athletic reports.
Ritchie will take the rotation spot of AJ Smith-Shawver, who is now being utilized out of the bullpen. Manager Walt Weiss also said Monday that Reynaldo Lopez (shoulder) may be headed to the injured list, which could result in Ritchie picking up another start after Wednesday before the regular season draws to a close.
