Diamondbacks ace Zack Greinke will start this season in the dugout.

Arizona manager Torey Lovullo said Monday that Greinke won't pitch on opening day because of what's perceived to be a minor health issue.

Greinke exited his latest start after one inning because of tightness in his groin. He's scheduled to pitch again in spring training Wednesday.

The Diamondbacks don't want to push him to be ready for their first game March 29 at home against Colorado. Without this wrinkle, Lovullo said Greinke would've started the opener for the third straight year.

"Every staff has a No. 1 and he fit the bill perfectly," Lovullo said. "He won 17 games last year. He was our staff ace."

Lovullo said he wasn't ready to say who would start against the Rockies. The likely candidate is Robbie Ray, who went 15-5 with a 2.89 ERA last year.

"There's a strategy," Lovullo said. "We don't just look at opening day. We look at opening day and then beyond, so probably five or six days beyond that day. And we want to make sure that we hit things just right to get it to the point where we have good matchups all the way through."
