Washington developer John Akridge yesterday told the D.C. Baseball Commission he has obtained the financial backing needed to go forward with his bid for an expansion franchise that would play at RFK Stadium permanently. The commission then unanimously approved Akridge's request for an endorsement, even though there is another group seeking to bring baseball to the Washington area.

The other group, Capital Region Baseball Inc., would like to initially locate a team at RFK Stadium, then move to a new stadium in Northern Virginia. That group said last week its finances are in order. Washington thus seems assured of two representatives in the race for one of two teams the National League will add in 1993.

The NL Expansion Committee has extended its application deadline from Friday to Tuesday at noon, NL spokeswoman Katy Feeney said yesterday. The extension was granted so interested groups would be able to work on their responses to a detailed questionnaire through the Labor Day weekend, she said. The responses must be returned with a $100,000 deposit on the $95 million entry fee.

Capital Region Baseball has not approached the D.C. Baseball Commission for support. But the commission, which gathered at the District Building for what Chairman Frank Smith termed an "emergency" meeting requested by Akridge, indicated such backing would not have been forthcoming as long as there was a viable group looking to use RFK Stadium on a permanent basis.

"The commission was created for one purpose -- to promote the District of Columbia as a site for baseball," said Smith, a D.C. councilman (D-Ward 1). "We have said all along we have been interested in a team that would play at RFK Stadium permanently."

Commission member Audrey Moore, chairman of Fairfax County's board of supervisors, did not attend yesterday's meeting. She was represented by Cliff Gaskins, chief of the county's mailing services office, and she said she approved of the commission's vote.

"I would hope" Capital Region Baseball "would be working with the commission to get one {a team} at RFK Stadium," Moore said. "I think RFK is the appropriate place to begin with. It serves the whole area. It's the logical place. It may not be the perfect place, but we can argue about that later. Maybe after a period of time, if RFK doesn't work, we can go to a better place. . . . The most important thing is to get baseball here. To be united is what I would would like to see us do."

Akridge declined to speak with the media yesterday, but said he would do so Thursday. He and Capital Region Baseball President Mark Tracz had discussed a merger in recent weeks, but they could not resolve their groups' differences about where a Washington franchise should be located.

Commission members declined to identify the investors Akridge told them he has attracted, but Donald Dell, a founder of the Arlington-based sports management and marketing firm ProServ, is said to be in the group.

"The group is complete," said Smith, adding that Akridge's group has raised $100 million. Commission member Richard Danker, a Washington restaurateur, said Akridge indicated a portion of the money has come from minority investors.

"From the beginning, we have been saying 'Baseball in Washington,' " Smith said.

"We have been working hard since 1984 to bring baseball to Washington," Danker said. "There is a stadium in Washington right now. There isn't one in Northern Virginia. But we won't have the final say. That will come from the baseball owners."

Tracz said he was not surprised by the commission's action, but expressed hope that Moore could be persuaded to change her position -- particularly since he and three other members of Capital Region Baseball's core group are Fairfax County residents. In addition, Capital Region Baseball is considering possible stadium sites in Fairfax, Loudoun and Prince William counties and in the City of Alexandria.
