Greinke brushes off contract extension talk

Right-hander is set to make $13.5 million in final year of deal

PHOENIX -- Zack Greinke still doesn't have an agent, and it doesn't sound as if he's in any hurry to hire one.

Greinke is entering his second season with the Brewers and the final season of his contract. If it expires, Greinke would be among the most coveted free agents on next year's market, but he expressed little urgency to settle his uncertain future following the Brewers' first workout for pitchers and catchers.

"I'm not even going to talk about that," he said after a midday mound session. "Sorry. I get annoyed when other people talk about it, and I already did earlier. It's the same stuff. Nothing has changed."

He was referencing Jan. 29, when Greinke spoke in fond terms about his first season with the Brewers during the team's "On Deck" event. He said then that he'd be willing to discuss an extension at some point.

But that may be difficult to do without an agent, considering the magnitude of a potential deal. Greinke, who was 16-6 with a 3.83 ERA in his National League debut last season, is set to earn $13.5 million for the second consecutive season.

He sees no reason to rush to hire representation.

"I'm not going to hire an agent for a while," Greinke said. "There's no reason to have one at the moment."

This spring should be decidedly different for Greinke, 28, who spent last year learning a new organization and then dealing with a cracked rib that was diagnosed in early March. He was hurt playing pick-up basketball.

"It seems like I was only here a week before I got hurt," Greinke said. "Maybe it was just a week before I got hurt, and I didn't know it until two weeks later. It was more dealing with that than anything."

This time around, he left his high tops at home and can focus on pitching. Greinke is working with pitching coach Rick Kranitz on a cutter, a pitch with which he's experimented before and never had much success. He's throwing three to five of them in each bullpen session, and was not pleased with the pitch on Monday.

Greinke also may tinker again with his curveball. Last year, he altered his grip and the result was a sharper, "better" pitch in every way but one -- when he threw it, hitters seemed to feast on it. Greinke said he may stick with the slower version this season.

He also spoke of a close relationship with manager Ron Roenicke, who, like Greinke, joined the Brewers last season. Greinke called his manager, "really, really, really smart."

"I know I was skeptical of what he would say sometimes, and if I don't agree with something somebody is saying, I usually tell them I think they're wrong," Greinke said. "There was one time I really remember, and probably two times, that I disagreed with him, and then a couple of weeks later I was like, 'You know what? I was wrong and he was right.' Now, if he says something, I assume he's right until it's proven wrong."
