Serena Williams bested her sister Venus again Sunday, winning the season-ending WTA Championships final, 6-2, 7-6 (4), in Doha, Qatar.  

Serena Williams broke serve twice in the first set and lost only seven points on serve in her last match of the year. She looked sharper than Venus in every facet of a match that featured few long rallies.

Serena Williams earned $1.55 million after finishing the event undefeated. She also clinched the year-end No. 1 ranking last week after Dinara Safina of Russia pulled out of the tournament with an injury in her first match. It was Williams’s third tournament win of the season after Wimbledon and the Australian Open.

 

 

 She sealed the match with a crosscourt forehand winner and celebrated calmly with a simple fist pump before hugging her sister at the net.

“It feels great,” said Serena Williams, who also won the WTA Tour’s season-ending event in 2001. “I totally didn’t expect to come here and win.”
