The Washington Kastles have won their third consecutive World TeamTennis title.
The Kastles defeated the Springfield Lasers 25-12 Sunday night in a match delayed two hours by rain.
Martina Hingis won her matches in singles, women's doubles and mixed doubles for the Kastles. She beat Alisa Kleybanova 5-2 in singles.
The Kastles weren't quite as dominant this year. They went 14-2 after going undefeated in both 2011 and 2012.
Earlier this season, the Kastles won their 34th consecutive match, which they claimed was the longest winning streak in ''major US pro sports history,'' surpassing the 33-game run by the 1971-72 Los Angeles Lakers in the NBA.
The streak ended the next day.
