Venus Williams has awed the world this year by reaching two Grand Slam finals at the age of 37. But for her, nothing about tennis has changed, and it's all about having fun (fun, fun, fun to be exact).

Williams made her World Team Tennis debut on Monday, playing for the Washington Kastles. She helped lead them to victory over the Philadelphia Freedoms, winning her singles and doubles sets.

The next day, in a loss against the Springfield Lasers, despite going up 4-1 over Sorana Cirstea, Williams dropped the singles rubber in a tiebreak. Williams also dropped the mixed doubles set with Bruno Soares, but won her doubles contest with Anastasia Rodionova.

The world No. 9 was playing in her 12th season of World Team Tennis.
