Charleston, S.C. -- After clawing her way back to into the match, No. 3 seed Venus Williams was taken out by Laura Siegemund in the third round of the Volvo Car Open on Wednesday.
Down 4-2 in the first set, Siegemund rallied to take the next four games, closing out the set 6-4.
In the second set, Williams fended off a match point at 5-3, and eventually sending the set to a tiebreak that the American won 7-6(3).
The third set was a topsy-turvy, which saw the players trade plenty of breaks as they struggled to hold serve. Up 5-4 and serving for the match, Williams was broken, with Siegemund winning the next two game to wrap up the match 6-4, 6-7(3), 7-5.
"I have no idea," said the German during her on-court interview on how she came through the tough match. "It was a really good match. It was going up and down. I just tried to believe in my game, and if I was down, I told myself I was going to get more chances."
There were 17 breaks overall in a match that took just over 3 hours.
Siegemund will next face Lucie Safarova, who triumphed over good friend and doubles partner Bethanie Mattek-Sands 6-3, 6-3.
