The entry fee for the two franchises the National League will add in 1993 has been set at $95 million each, and representatives of two Washington area groups seeking a team said yesterday they will have to reexamine their plans.

The price tag -- more than has ever been paid for a major league franchise -- was revealed in a questionnaire mailed late Wednesday from the league to 26 prospective ownership groups in 10 cities. In addition to Washington, those cities are Buffalo, Denver, Miami, Nashville, Orlando, Phoenix, Sacramento, St. Petersburg/Tampa and Vancouver. Prospective ownership groups have 30 days to respond to the questionnaire, which must be returned along with a $100,000 application fee.

Although the entry fee will guarantee each of the new teams 36 players from the 12 existing NL clubs, it appears that before spending a penny on player salaries or a minor league system, the new owners will have paid $20 million more than the San Diego Padres fetched when they were sold earlier this summer and about 14 times more than the Toronto Blue Jays and Seattle Mariners paid when they joined the American League in 1977. The Blue Jays had to pay $7 million. The Mariners, who had to pay $6.25 million, were sold last fall for a reported $76.1 million.

"They are asking $95 million for something that is not going to be competitive right away and is without a history," said Sovran Bank President Robert Pincus, who is trying to organize an ownership group for a team that would play at RFK Stadium. "I think a lot of regions are going to have a hard time coming up with that. . . . I'm not saying it will discourage us, but we will have to sit down and reevaluate that now."

His group, which is connected with the D.C. Baseball Commission, also includes developer John Akridge, who said: "No matter what, $95 million is a lot of money. It might be worth it. It might not."

The leader of Washington's other prospective ownership group reacted in similar fashion.

"Considering the sale of a team {the Padres} for $75 million got approved two months ago, it's puzzling to me how they can ask for $95 million," said Mark Tracz, owner of the Prince William Cannons of the Class A Carolina League and leader of Capital Region Baseball Inc. That group, composed of Washington area businessmen, is seeking a team that Tracz hopes would begin playing at RFK Stadium, then move to a new facility in Northern Virginia. "We're in a tough economy right now. This is not the time to be frivolous with money."

Pincus and Tracz said they had been anticipating an entry fee of about $70 million. They figured cash investments and financing totaling $100 million would give them enough money to operate and a reserve to cover losses anticipated in the first few years. Now, they will have to raise even more money in an area where many potential investors are involved in real-estate development, a business that has come upon hard times recently.

Tracz said that unless his group ultimately can raise between $35 million and $50 million in cash it will be unable to pay for a team. Councilman Frank Smith (D-Ward 1), chairman of the D.C. Baseball Commission, has said many times that if the D.C. group cannot make a viable presentation to the NL Expansion Committee it will not make one at all.

Douglas Danforth of the Pittsburgh Pirates chairs the expansion committee, whose other members are NL President Bill White, John McMullen of the Houston Astros and Fred Wilpon of the New York Mets. The committee will hear presentations from prospective ownership groups by Sept. 30, make initial findings by Nov. 30 and reveal a list of three, four or five finalists by Dec. 31. The franchises are to be awarded by late summer 1991.

All parties concerned with the Washington area's bid for a team agree that a key to its success is a merger of the two groups resulting in the submission of one questionnaire. Tracz said there are potential investors "sitting on the sidelines waiting for us to get together."

There have been at least two meetings between various members of the two groups, but there has been little progress on their disagreement about where the team should play. Tracz said a proposal to submit a joint questionnaire that essentially would allow the major league owners to decide whether they prefer RFK Stadium or Northern Virginia was rejected by the D.C. group.

He said if the D.C. group "remains insistent" on permanently locating a team at RFK, "our groups won't merge." He said he hopes an agreement can be reached.

"Washington will benefit from one application rather than two," Akridge said. "Whether that can be worked out, I don't know. I'm not in a position to make any kind of a prognostication at this moment."

RFK Stadium General Manager Jim Dalrymple said a little more than a month ago the D.C. group and the D.C. Armory Board had agreed to terms on a lease for the use of the stadium if the D.C. group is awarded a team. The deal was awaiting final approval from the armory board, composed of Mayor Marion Barry, Maj. Gen. Calvin Franklin of the D.C. National Guard and businessman Stuart Long.

The Northern Virginia group also has been seriously involved in stadium plans. Tracz said yesterday it has a 170-acre parcel of land near Dulles Airport under contract with an option to buy. The land is owned by a partnership whose principals include developer William Bryant, one of the group's main financial backers, Tracz said.

A site in Lorton and one near Fort Belvoir also are being considered by the Northern Virginia group, which has retained the services of a stadium architect and a financial consultant and is negotiating with an engineering firm.
