Sister-Sister Duel In Doha

This time it's for the title.

The top eight women's tennis players in the world have been in Doha, Qatar this week playing in the WTA Championships.

The format of this tournament split the eight women into two groups, with everyone in the Maroon and White groups playing each other in a round robin format. Top two in each group met in the Saturday semis to determine who played in the championship match today.

When all was said and done, my favorite tennis playing sisters were the last ones standing and will face off for the WTA Championship.

The Williams sisters were placed in the same Maroon group and faced each other in round robin play Wednesday. Little Sis had to work to beat Big Sis, 5-7 6-4 7-6(4) and raise her all time record against Venus to 12-10.

In the semis Serena needed only 45 minutes in her semifinal as she took the first set from Caroline Wozniacki before she retired due to abdominal strain two games into the second set.

Venus on the other hand outlasted Jelena Jankovic 5-7 6-3 6-4 in her semifinal match which took 2 hours and 34 minutes to play.

So once again the Williams sisters are playing each other in the championship match of a tournament. What's also cool is that no matter what happens today, Serena will finish the year ranked Number one in the world.

So my prediction for today's match? Someone with the last name of Williams will win it.
