Serena Caps Year With WTA Championships Win

It's becoming a recurring theme lately for the Williams sisters. Little Sis beats Big Sis.

This time it was for the WTA Championship in Doha, Qatar.

Serena met her older sister for the second time in this tournament and won in straight sets 6-2, 7-6 (4) in the season-ending WTA Championship final.

"It feels great," said Serena, "I totally didn't expect to come here and win."

Both sisters were nursing injuries while getting to the final in different ways. Serena went unbeaten in the tournament and only dropped one set while doing so to Big Sis.

Despite losing two round robin matches and being extended to three sets in all of them, defending champ Venus still made it to the final of this tournament.

"It was the end of the season, so I have no complaints," Venus said when questioned about her fitness level. "You have to show up and play no matter what. So that had nothing to do with it."

It was Serena's fourth straight victory over Venus and pushed her all time record in their head yo head matchups to 13-10. It was also not only Serena's first win in a non-Grand Slam tournament this season, it was her first win in the WTA Championships since 2001.

"I haven't won a tournament that wasn't a Grand Slam in a while, so that was even more exciting," she said. "My losing streak in (other) tournaments in over."

That's bad news for the rest of the women's tennis playing world. But y'all have two months to rest up before the 2010 Australian Open starts Down Under.

And so do the Williams sisters.
