SYDNEY -- D-backs reliever J.J. Putz has not pitched well this spring, but the right-hander said he believes things are turning around.
Putz made a few mechanical changes this spring, and he believes that thinking about them too much while pitching has led to the struggles.
"You make a bad pitch and your mind starts going back over all the mechanical checkpoints instead of just throwing free and easy," Putz said. "Now it's time to put that in the past and just go."
That doesn't mean that he scrapped the changes.
"It's to the point now where I think the muscle memory has kind of taken over to the point where I don't have to think about it very much," Putz said.
Putz is set to throw a simulated game Thursday, his last tuneup before the regular season gets started Saturday.
"I think it will be good just to get on the mound here with the backdrop and see the visual from the mound to the plate," he said.
