Trevor Cahill isn't stupid. He knows what people are saying about him, even if he swears he rarely reads the sports pages or listens to much sports-talk radio.

"When things are going bad," the Diamondbacks right-hander said, "I'm definitely not looking at any of the media stuff. I try to keep my head out of that stuff."

And, yes, things are going bad. Entering Sunday's start against the Dodgers, Cahill is 0-3 with a 7.90 ERA. It's been so confounding that the Diamondbacks have contemplated moving him out of the rotation, just like they officially did with Randall Delgado on Friday night.

Cahill wouldn't say that he felt any sort of sigh of relief because it was Delgado moving to the bullpen and not him.

"My approach is pretty easy," he said. "I prepare as best as I can and go out there and compete as best I can. That's all I can do. When it's going good, it's going good. If it's not, it's not. But no matter what, I come here trying to be a good teammate and a good person."

On back-to-back days, Cahill has received a vote of confidence from both General Manager Kevin Towers and manager Kirk Gibson, each of whom said they believe the 26-year-old will pitch his way back to form and rediscover his location.

But are they saying that because they truly believe it or because there's simply no more room in the bullpen and Cahill probably isn't a good fit there, anyway? It's not like they have a capable, electric arm at the ready to plug into the starting rotation.

After all, it seems obvious the organization has no intention of rushing prized prospect Archie Bradley to the majors. They won't let him pitch here until they deem him absolutely ready and besides, they aren't crazy about starting the clock on his big-league service time.

For now, the Diamondbacks have no choice but to stick with Cahill, who still has very good stuff when he can command it.

"He just hasn't been able to put it together with any kind of consistency yet," Gibson said Saturday, adding, "We see him repeating his delivery more; he's making progress."

Cahill is making some subtle changes to try and get him dialed in but he isn't putting any more importance on this start than any of his previous three.
