Venus Williams beats Serena in Nigeria exhibition, declares 2013 'going to be a great year'

Venus Williams danced and smiled during an exhibition win against her sister Serena in Nigeria's largest city.

Venus won 6-4, 7-5 Friday at the Lagos Lawn Tennis Club despite 91-degree heat that felt like 101. She appeared loose during play, dancing at an intermission, joking with the umpire and playfully teasing her sister.

Venus says her win shows that 2013 "is going to be a great year."

Serena grew frustrated by her play, several times kneeling on the clay court and pressing her head against her tennis racket. However, she did a double-take and laughed when she saw a sign in the crowd from a man declaring to be her "Nigerian husband."

The sisters move on to South Africa as part of their two-nation tour.
