Venus Williams helped Washington catch up, then beat Coco Vandeweghe in a last-game tiebreaker as Washington completed its second straight undefeated championship season in World Team Tennis with a 20-19 victory over Sacramento on Sunday.
Washington (16-0) has won 32 straight matches the past two seasons.
Williams, the seven-time Grand Slam champion, was front and center for Washington's latest title run. She teamed with Anastasia Rodionova to win the women's doubles match 5-1. After Western Conference champion Sacramento moved ahead 11-10 with a 5-2 win in men's doubles, Williams and Leander Paes took the win in mixed doubles in a last-game tiebreaker to square the finals at 15-games apiece.
It took one more extended match to clinch things for Washington as Williams wrapped up the crown.
