DENVER (AP) - The Arizona Diamondbacks activated pitcher Yusmeiro Petit from the disabled list and will start him Saturday night against Colorado.
To make room for Petit on the roster, infielder Ryan Roberts was optioned to Triple-A Reno.
The right-handed Petit has been on the disabled list since May 9 with a strained right shoulder. He's 0-3 with an 8.03 ERA this season.
Roberts was hitting .257 with no homers and five RBIs this season with Arizona.
