PHOENIX -- With their bullpen back at full strength, the D-backs optioned left-handed pitcher Tyler Skaggs back to Triple-A Reno and recalled outfielder Tony Campana.
Campana was with the D-backs for a brief stint at the beginning of July, appearing in two games and going 3-for-10 at the plate.
Skaggs, who was called up Monday to provide depth in the bullpen, did not appear in a game.
Campana gives the D-backs an extra bat, as well as speed off the bench. With Reno, he was 32-for-40 in stolen-base attempts.
"That's an elite tool that he possesses," D-backs manager Kirk Gibson said of Campana's speed. "Looking at who we could bring up that's ultimately why we did it. He does bring energy, creates havoc, good bunter, can steal bases."
