A group of Washington-area businessmen seeking a baseball expansion franchise for Northern Virginia has obtained the necessary financial backing to apply for one of the two teams the National League will add in 1993, one of the group's organizers said yesterday.

"As of today {Friday}, we have the commitments we need and we are going forward," said Ira Saul, vice-president of Capital Region Baseball, Inc. "It is a certainty our application will be going in."

This development comes a week before the NL Expansion Committee's deadline for responses to a detailed questionaire that must be accompanied by a $100,000 deposit on the $95 million entry fee. It means the capital area is almost assured of having two well-financed bids for a team.

Washington developer John Akridge and Sovran Bank President Robert Pincus are leading a group that would like to put a team at RFK Stadium. That group was "pretty close" to reaching its goal of having $100 million to $125 million in cash, Pincus said earlier this week.

Saul declined to identify who clinched the deal for his group, which has been negotiating with potential investors in the Washington area, throughout Virginia, in New York City and other parts of the nation. But Saul said it is one individual who is the group's "main financial backer" and has put the group in position to have in cash the $125 million to $150 million Saul said it will need for the entry fee and initial operating capital.

"We believe the franchise to be an equity deal," said Saul, who added the group remains open to other investors.

All of this represents a significant change in position for Capital Region Baseball. Several weeks ago, its president, Mark Tracz, said his group's goal was to raise $35 million to $50 million in cash. He also expressed concern about its ability to reach that goal.

"There have been some frustrations in putting things together," Saul said, "but we are very excited. It's been a long time coming."

Although the group has been negotiating with potential investors outside the Washington area, Saul said the group will satisfy baseball's preference for local ownership.

"We will have substantial local ownership," Saul said. "We're well aware of that criterion."

They also are well aware of their need for a facility in which to play. Akridge's group has a letter of understanding with the D.C. Armory Board for a relatively long-term lease on RFK Stadium. But the stadium's general manager, Jim Dalrymple, has indicated the letter will not preclude negotiations for a short-term lease if Capital Region Baseball is awarded a Washington franchise.

As for a new facility, Capital Region Baseball already has a 170-acre site near Dulles Airport under contract. Saul said his group also is examining a total of five or six sites in Loudoun County, Fairfax County and the City of Alexandria. He added paying for the stadium will not be a problem.

"The stadium is a financeable entity," he said. "The stadium will take care of itself once the franchise is established."
