SURPRISE, Ariz. -- Rangers general manager Jon Daniels, who received a four-year contract extension a week ago, said nothing will change in the way the club conducts baseball operations in the wake of the resignation of club CEO Chuck Greenberg.

Daniels said baseball operations should be unaffected by the change, which the club announced on Friday. Greenberg is stepping down as CEO and managing partner while selling his shares back to other partners in the Rangers' ownership group.

"It shouldn't have an impact," Daniels said. "It's not going to change how we operate. We have an organizational structure and a budget. All of that remains the same."

Greenberg put together the ownership group that bought the Rangers from then-owner Tom Hicks last August. The group is known as Rangers Baseball Express, with Greenberg as the CEO, Nolan Ryan as club president, and Ray Davis and Bob Simpson as co-chairmen of the Board of Directors. Ryan will take over as CEO.

"Ownership change is not that unusual," Daniels said. "They happen in the game, or in any business. This change has been stretched over a long period of time ... longer than anybody anticipated. But going forward, I think we're set up for stability."

Under the old arrangement, Ryan was going to be in complete charge of baseball operations while Greenberg would concentrate on the business side. But Greenberg took an active role during negotiations with free-agent pitcher Cliff Lee this winter. Lee ultimately signed for less money with the Phillies.

Daniels said Greenberg's involvement in the negotiations did not create any concerns. Daniels has been reporting directly to Ryan for the past three years, and that will continue.

"Cliff had some very attractive options and he made a choice for him and his family," Daniels said. "I wasn't concerned with that."

Daniels said Greenberg's involvement in baseball decisions was "about what you would expect" for somebody who represented ownership.

"He was in the office when decisions were made," Daniels said. "Some Chuck had an opinion on, and some he didn't. Ultimately, as a group, we put our heads together and made baseball decisions. Big investments and big dollars typically involves ownership to a degree.

"Personally, I had a very good relationship with Chuck. He put a lot of time and effort to spearhead the [ownership sale] through ... but I have a very good relationship with Nolan, and the interaction with the ownership group has been positive."
