Venus Williams secured her place in the semifinals of the Sony Ericsson Championships with a 5-7 6-1 6-0 win over her sister Serena on Thursday.
It was the first time in eighteen meetings between the Williams sisters that one of them took a set without losing a game. Also, it was the first time Serena lost a set 6-0 since the 2007 Miami final against Justine Henin, which the American eventually won.
Today’s clash with sister Venus Serena considers her worst performance this year.
"I don't think I've ever played like that," said third-seeded Serena.
"I've never been in a situation where I just feel like I can't do anything. Today I couldn't serve, I couldn't hit a backhand, I couldn't hit a forehand, I couldn't even volley. This is definitely the worst match I've played this year by far."
In two other Thursday’s matches Jelena Jankovic beat Svetlana Kuznetsova and made it to the semifinals, while Elena Dementieva ended Dinara Safina’s 2008 tennis season in straight sets with a 6-2 6-4 win.
Besides Venus Williams and Jelena Jankovic, Vera Zvonareva has also qualified for the semifinals of the Sony Ericsson Championships. The fourth semifinalist will be either Serena Williams or Elena Dementieva. (source: Reuters, photos: Getty Images)
