Venus, Jankovic reach Sony Ericsson semifinals
DOHA, Qatar -- Venus Williams defeated her sister 5-7, 6-1, 6-0 on Thursday to reach the semifinals of the WTA Tour's season-ending Sony Ericsson Championships, a match Serena Williams called her worst of the year.
Serena started to unravel early in the second set.
"I just couldn't keep a ball in play," she said. "Everything was off."
Venus won on her fifth match point and is 3-0 in round-robin play of a tournament that features the top eight players. Serena dropped to 1-1 but can still advance to the semifinals if she defeats Elena Dementieva on Friday.
Dementieva defeated Dinara Safina 6-2, 6-4 in Thursday's last match, eliminating Safina from the championships.
The Williams sisters are 9-9 in career matchups. Serena defeated Venus in the U.S. Open quarterfinals en route to the title this year, and Venus won their title match at Wimbledon.
Venus stayed composed throughout the match, using her powerful serve to frustrate Serena, and refrained from celebrating after winning."It wasn't the happiest match," Venus said. "The best part is that she still has an opportunity to qualify."[+] EnlargeKarim Jaafar/Getty ImagesSerena Williams called the match her worst of the year, but she can still advance to the semifinals if she wins her next match.
Both sisters played their trademark power tennis in the first set before the rallies turned shorter in the second, with Serena growing increasingly frustrated by her errors.
Venus earned two set points in the second when Serena double-faulted and converted the second with a cross-court backhand that passed her younger sister at the net.
"I didn't even look like a top-eight player today. Maybe top 600, in the juniors," said Serena, who has won nine majors and is making her fifth appearance at the season-ending championships. She won the event in 2001.

"I hope I will be OK" for the semifinals, Jankovic said.
Kuznetsova has one more round-robin match to play but can't advance because she's lost twice.
Eight players are divided into two groups, with the top two in each group advancing to the elimination stage.
