The No. 4 seed blamed the loss on being exhausted.
CHARLESTON, S.C. (AP) -- Defending champion Venus Williams blamed exhaustion for her upset loss Thursday to Tatiana Golovin at the Family Circle Cup.
Williams lost 7-5, 6-4 on a blustery day. It was the first time this year that Golovin, a Frenchwoman ranked No. 25 in the world, had beaten a top-10 player.
"I just kept making error after error. It was a comedy of errors," said the fourth-seeded Williams, who played Wednesday night and then had to play again at 1 p.m. "It was windy out there and I just had a quick turnaround from the last match and my feet never moved."
Williams, ranked No. 8 in the world, said she had a mental letdown during the match because of all the tennis she has played in the past four weeks.
"I just felt pretty dead," Williams said, quickly adding with a laugh: "But I'm alive."
It was the first career meeting between Williams and Golovin.
"I have played against a few top-10 players already and, you know, I always kept losing in three sets," Golovin said. "I think I was just more really ready to beat a top-10 player."
Golovin advanced to play seventh-seeded Nadia Petrova of Russia in today's quarterfinals. Petrova was a 6-3, 6-3 winner over Jelena Kostanic of Croatia.
Justine Henin-Hardenne, who spent much of last season ranked No. 1, defeated Iveta Benesova 6-2, 6-3 and faces No. 1 seed and top-ranked Lindsay Davenport.
Davenport dispatched qualifier Viktoriya Kutuzova 6-3, 6-1 in Thursday's late match.
"I feel I'm playing pretty well. Clay is not my favorite. But I feel like I'm hitting the ball well," Davenport said. "I'm coming off a win at Amelia Island and I'll just keep trying to be aggressive and hopefully things will work out."
In the other bracket, Patty Schnyder, seeded eighth, was a 6-4, 6-0 winner over Klara Koukalova and will meet 15-year-old Nicole Vaidisova who defeated No. 14 seed Shinobu Asagoe 3-6, 6-4, 7-6 (2).
On the same side of the draw, Katarina Srebotnik, a 6-1, 4-6, 6-1 winner over Ai Sugiyama, meets No. 2 seed Elena Dementieva who defeated Nuria Llagostera Vines 6-0, 6-3.
