Mets starting pitcher Rafael Montero resumed a rehab assignment in the Gulf Coast League on Thursday, making his first appearance since July 20.

The right-hander tossed two scoreless innings, allowing one hit and no walks. He also had one strikeout. He has not allowed a run through six innings (three appearances) in the Gulf Coast League.

Montero has been on the disabled list since late April due to rotator cuff inflammation in his right shoulder.
