NEW YORK, SEPT. 1 -- The 1987 Sovran Bank/D.C. National Classic was easily the most successful in the Washington tournament's 19-year history. With Ivan Lendl, Boris Becker and Jimmy Connors in the field, the event broke all its attendance records, selling out virtually every session.

According to sources here, ProServ Inc., which manages and runs the tournament for the Washington Area Tennis Patrons Foundation, will realize a profit of close to $200,000 after expenses and after the Patrons are given their share of the profits, which should be well more than $100,000. That money will go toward promoting junior tennis in the national capital area.

ProServ officials, when quoted the $200,000 figure today, said they did not know if it was accurate. "I really don't know if that figure is correct yet," said Gerry Solomon, ProServ's executive vice president. "It usually takes at least 60 days for us to get final figures on an event we run and it's only been 30 days or so since the tournament ended.

"Certainly the tournament was a major success. We think it's become a major social event in Washington. People like to come out and see the tennis and there's no question the switch to hard court and the quality of our field helped. But exactly how much money we made I just don't know for sure yet."

As recently as four years ago, sources say, ProServ's profit was only about $40,000. But with increased revenues from ticket sales, concessions and television, the profit level has jumped, especially with the record-setting crowds this year. Solomon said he could not remember how much revenue ProServ realized from last year's tournament.

Chip Hooper, the 6-foot-6 one-time wonder who made a name for himself at Wimbledon in 1982 by upsetting then seventh-ranked Peter McNamara in the opening round and reaching the round of 16, got into the U.S. Open today when Kevin Curren withdrew because of a knee injury.

Hooper was the highest-ranked player (140th) to lose in the last round of qualifying. So, when Curren withdrew, he got in as a lucky loser. He will play Andrei Chesnokov of the Soviet Union on Wednesday . . .

Other qualifiers included Alexander Volkov, the Soviet who reached the round of 16 at Wimbledon by beating Brad Gilbert. Another was Jim Gurfein, the American who was injured on a tennis trip to Nigeria when he jumped through a window in the midst of a religious ceremony. And another was John Ross, who commuted between a tournament in Westchester, N.Y., and qualifying here last weekend, playing two matches on Saturday and two on Sunday. Gurfein lost today. Volkov and Ross play Wednesday . . .

Tim Wilkison before he played Boris Becker tonight: "You better tell people that if they want to see Boris play here that they better get out here on Tuesday because he's going out." Then, pausing, "That sounds good doesn't it? Sort of like professional wrestling."
