Serena Williams passed her first test of the French Open, beating two-time major champion Svetlana Kuznetsova 6-1, 3-6, 6-3 in the quarterfinals Tuesday. Roger Federer wasn't as fortunate, losing to Jo-Wilfried Tsonga 7-5, 6-3, 6-3. This was Federer's first straight-set loss at a Grand Slam tournament to someone other than Rafael Nadal or Novak Djokovic since the 2004 French Open, when Gustavo Kuerten swept him in the third round.

In the undercard matches, David Ferrer crushed fellow Spaniard Tommy Robredo 6-2, 6-1, 6-1, and Sara Errani eliminated No. 4 Agnieszka Radwanska 6-4, 7-6 (6) for her first career victory against a top-five player after 28 losses.

Serena Williams: Kuznetsova rallied from a set down and led 2-0 in the third before Serena stormed back to win. "Today I was so determined to get through that [rough patch] and I really, really, really, really wanted it more than I think anyone," Williams said. She's into the semifinals of the French Open for the first time since 2003. "I just got tired of losing in the quarters," she said. (Julian Finney/Getty Images)

David Ferrer: Don't look now, but Ferrer is into the semifinals without dropping a set, and he won't have to play a member of the Big Four next. He'll face Tsonga for a spot in the finals. (Miguel Medina/Getty Images)
