Nate Pearson pitched in a live game for the first time this season as he began a rehab assignment in Single-A with Dunedin.
Pearson went 1.2 innings allowing an earned run and a walk while recording a strikeout on 30 pitches.
The 25-year-old has been working his way back to pitching after getting sidelined during spring training with mononucleosis.
He had been going through an extended spring training and is expected to return to the Blue Jays in a multi-inning role out of the bullpen.
