The Washington Kastles won their fourth straight World Team Tennis championship Sunday night in Springfield, Mo., beating the Springfield Lasers, 25-13. The title is their fifth in six years and a fourth consecutive championship ties the 1997-2000 Sacramento Capitals for the longest title run in league history. The Kastles won all five of their sets in the match.

The Kastles kept their core lineup from 2013 for this season, leaning on Anastasia Rodionova, Leander Paes, Bobby Reynolds and Hall of Famer Martina Hingis. Kevin Anderson, Sloane Stephens and Venus Williams also played for the Kastles in at least one match.

The season had its bumps along the way. The Kastles dropped four matches — two more than the last three seasons combined — and they had no players receive WTT individual honors.

There will be at least one major change to the roster next season. After five seasons, Reynolds announced his retirement after the Eastern Conference championship. In his final men’s singles set, Reynolds beat Springfield’s Michael Russell, 5-4, to give the Kastles a lead after the first set. Hingis rebounded from a two-game deficit to win the women’s singles match, 5-2, over Olga Govortsova.

The Kastles rolled from there, winning men’s doubles, 5-2; women’s doubles, 5-1; and mixed doubles, 5-4.
