PHOENIX -- Right-hander Randall Delgado will get another chance to make a lasting impression when he gets the start Tuesday against the Marlins.
Delgado, who lost out in his bid to win the No. 5 spot in the rotation during Spring Training, was called up briefly earlier this month and made one relief appearance before being sent back to Triple-A Reno.
"Delgado was up here and got his feet wet this year, went back down worked on some things, threw a good game, [had] better command and he's the guy," D-backs manager Kirk Gibson said.
Delgado will take the place of Tyler Skaggs in the rotation. Skaggs was sent to Reno last Monday when the team added Charles Brewer to bolster a tired bullpen.
Josh Collmenter was thought to be the frontrunner to make the start, but Gibson decided he was more valuable in his long-relief role.
"He's really good at what he does, you could say arguably as good as there is," Gibson said of Collmenter. "You get into an extra-inning game, you put Collmenter in there and he's won three of them for us. He's done his job. I think, ultimately, if you moved him into a starter's role, then you had to take someone to fill his role and then you're filling two roles and here we're just filling one."
Gibson would not commit to Delgado past Tuesday's start. Due to the rule that says an optioned player must remain in the Minor Leagues for 10 days after being sent down, Skaggs is not able to be recalled until Thursday at the earliest.
