Serena Williams

hasn't played the French Open in 3 years and hardly seems ready for this month's clay-court major.

She made an array of mistakes yesterday in her final match before the French Open, losing to Patty Schnyder, 6-3, 2-6, 7-6 (5), at the Italian Open quarterfinals in Rome.

"I'm going to obviously want to work harder and just do some things differently," Williams said. "Where I am today, in Paris I'll probably be even better."

In the semifinals, Schnyder will face third-seeded Jelena Jankovic, who routed Elena Dementieva, 6-2, 6-1. Second-seeded Svetlana Kuznetsova beat sixth-seeded Dinara Safina, 6-1, 6-3, in an all-Russian match and will next play ninth-seeded Daniela Hantuchova, who beat unseeded Anabel Medina Garrigues, 7-6 (8), 7-5.

It was only Williams' third loss this season. She began 2007 by winning the Australian Open for her first major title in 2 years.

"I just didn't make the shots I was supposed to make," said Williams, who was seeded eighth. "I probably made 50 unforced errors, which is pretty good to get to 7-6 in the third."

Schnyder, seeded 14th and runner-up in Rome 2 years ago, beat Williams in their only previous match on clay. Williams won the other six meetings

"I have more time to think and I think it's her weakest surface," Schnyder said. "I'm extremely happy that I could do it again this year because she's the champion to beat this year."
