CHARLESTON, S.C. (AP) The Washington Kastles completed the first perfect season in World Team Tennis, defeating the St. Louis Aces 23-19 on Sunday night to win the series championship in a match that took nearly eight hours to complete because of several long rain delays.

The final began at 5:20 p.m. and lasted until Bobby Reynolds' winner at around 1:05 a.m. to the cheers of a few hundred fans who remained at Family Circle Stadium. The Kastles ended the year 16-0, the first team since the WTT began in 1974 to go through a season without a loss.

Washington's squad lasted through three rain delays totaling four hours in a city which last year won the honor as the "Best Tennis Town in America."
