Diamondbacks selected the contract of RHP Dennis Santana from Triple-A Reno.

Santana was inked to a minor league contract last week after he elected free agency from the Pirates. While he has struggled to a 6.05 ERA over 41 2/3 innings on the season, he has proven to be a viable late-inning option in the past and could work his way into the saves mix with the Diamondbacks if he pitches well out of the gate.
