The Cubs optioned Wingenter to Triple-A Iowa on Monday, Sahadev Sharma of The Athletic reports.
Wingenter has made five relief appearances for the Cubs this season, allowing two runs with a 3:2 K:BB over six frames. He had pitched both of the last two days, so the Cubs are replacing him with a fresh arm in Gavin Hollowell, who was recalled from Triple-A in a corresponding move.
