Top-seeded Pam Shriver won the 15th singles title of her career yesterday as she became the first woman to take back-to-back Virginia Slims of Newport tennis tournaments since the event began in 1983.

Shriver, 25, of Lutherville, Md., defeated eighth-seeded Wendy White of Fort Worth, Tex., 6-2, 6-4, and earned $30,500 for the title in Newport, R.I. White, 26, playing in only the third final of her career, earned $13,800.

Shriver, who has beaten White in all of their eight career matches, needed only one hour to win her second title of the year. "It's always straight sets but respectable straight sets," Shriver said of her rivalry with White.

White failed to capitalize on the break points she had in three of Shriver's four service games in the first set.

"I wish I had taken advantage of those but she served very well on the break points," White said. "I guess that's her confidence and match experience. She played the big points really well."

Shriver broke White's serve in the second game of the first set. In the second set, Shriver lost her serve in the third game, but she broke back in the fourth. She broke White again in the 10th game and ended the match with a backhand smash down the line.

U.S. Clay Court Championship:

Sweden's Mats Wilander, breaking service four times in a shaky first set, outlasted countryman Kent Carlsson, 7-5, 6-3, in the final in Indianapolis.

Neither player served effectively in the first set, and Carlsson, who broke Wilander three times, tied it at 5-5 after surviving a triple set point. With the court temperature at 118 degrees, the top-seeded Wilander, 22, held serve at 6-5 and broke the third-seeded Carlsson at deuce on the next game to take the first set.

Wilander, who won $51,000, is 39-0 in matches in which he has won the first set.

He started the second set by holding serve, then took control by breaking Carlsson and holding again for a 3-0 lead. It was Wilander's 26th career singles title -- and 18th on clay.

Volvo-New Jersey Championship:

In Livingston, N.J., top-seeded Johan Kriek of Naples, Fla., defeated unseeded Christian Saceanu of West Germany, 7-6, 3-6, 6-2, to win his first tournament in more than two years.

Saceanu, 19, ranked 167th in the world, had two set points in the 12th game of the opening set and confused Kriek during the 2-hour 10-minute match. Kriek, who had 16 aces, held off Saceanu by serving superbly.
