Collmenter is expected to return sometime in the middle of the team's upcoming nine-game road trip, Scott Bordow of the Arizona Republic reports.

EDGE Analysis

Collmenter will pitch three innings for Single-A Visalia on Monday, then the team will likely want him to make one more rehab appearance before rejoining the big league roster. When he returns, Collmenter will give the Diamondbacks an experienced long relief option out of the bullpen.
