Trevor Cahill's stint in the minor leagues is over as the Diamondbacks announced Monday the right-hander has been recalled from Triple-A Reno and will start on Friday night vs. the Chicago Cubs at Chase Field.

To make room, the Diamondbacks optioned right-hander Mike Bolsinger to Reno.

A month ago, the Diamondbacks took Cahill out of their bullpen and sent him to the minors, where he built up his pitch count in order to return to the rotation.

There was hope he would also be able to iron out the command issues that have plagued him for more than a season and a half. On that front, the results aren't encouraging.

Cahill made one start with High-A Visalia before moving to Triple-A Reno. All told, he had a 4.45 ERA in 30 1/3 innings in the minors, with 20 walks and 27 strikeouts.

The Diamondbacks sent Cahill to the minors with the understanding he would be brought back to the majors at a specified time.
