CHARLESTON, S.C. (AP) -- Venus Williams has lifted the undefeated Washington Kastles to the World Team Tennis final with a 19-15 victory over the New York Sportimes.

Williams won the women's singles, the final match Saturday night, 5-1 over the Sportimes Ashley Harkleroad to keep the Eastern Conference champion Kastles' winning streak intact. The teams were tied at 14 going into the final match.

The Kastles, 15-0 on the season and winners of 31 straight WTT matches, will face the Sacramento Capitals on Sunday in the championship. The Capitals beat the Orange County Breakers 25-15 on Friday.

Williams's serve was broken in the first game of the final match, giving the Sportimes their first lead of the night. But she won the next five games to put the Kastles into the championship.
