Gibson not ready to name starter for Sunday's game

PHOENIX -- The D-backs have not announced a starter for Sunday's series finale with the Reds, but Randall Delgado would seem to be the natural choice given his performance Tuesday night.

Delgado allowed two runs on eight hits over seven innings against the Marlins.

"We haven't talked about it," manager Kirk Gibson said when asked who would start Sunday. "It's possible he could start again, but it hasn't been determined. A lot depends on how we get through the weekend."

Delgado had battled for the No. 5 spot in Spring Training, but he struggled with his command and lost out to Patrick Corbin.

When the D-backs needed a bullpen arm earlier this month, Delgado was called up from Triple-A Reno, and he made one appearance before being sent back down.

Delgado showed excellent control Tuesday by not issuing a walk and while he has made some mechanical adjustments since the spring, that was not the main reason for his improvement.

"I tried everything, but I think it was more mental," Delgado said. "When you get confidence, you feel better. It's not so much about mechanics, it's more about being confident."
