Stripling threw five shutout innings for the Buffalo Bisons, allowing three hits and no walks with three strikeouts.
The appearance was Stripling's first game action since he pitched 4.1 innings in a start on July 30. He was placed on the 15-day IL on Aug. 3 with a glute injury and hip strain.
Stripling has rebounded into an effective starter for the Blue Jays this season, filling in for the injured Hyun-Jin Ryu. In 23 games this season — including 15 starts — he has a 5-3 record with a 3.16 ERA and 67 strikeouts.
Speaking after the Blue Jays' loss to the Guardians, interim manager John Schneider said the performance was "vintage Strip."
"We're hoping that today was all he needed and he gets back with us as soon as he can," Schneider added.
