Novak Djokovic was in celebratory mood Wednesday and why not? He became only the second man to beat Rafael Nadal at the French Open.

In the women's draw, Serena Williams cruised past 2012 finalist Sara Errani to reach the semifinals. The world No. 1 hit 10 aces and looked extremely comfortable from the back of the court.

Djokovic's athleticism, shot-making and court coverage were just too much for Nadal. He won in straight sets to end a 0-6 skid against the Spaniard at Roland Garros.

It was a 29th birthday to forget for Nadal, the nine-time champion at Roland Garros. His last and only other loss at the French Open came in 2009 against Robin Soderling.

Nadal was mostly on the defensive, apart from a spell in the first set when he won four straight games to go from 0-4 to 4-4.

Nadal vowed to "fight" to get back to winning ways. He'll now think of the grass-court season, which begins Monday.

Djokovic, meanwhile, meets Andy Murray in the semis. Murray beat David Ferrer for the first time on clay, in four sets. Murray is yet to lose during the clay-court season.

When Ferrer missed two set points in the first set, Murray kicked on. The 2013 finalist managed to save a set point in the third but lost the fourth set in lopsided fashion.

Wednesday was a contrast to the previous rounds, when Williams lost a set to three players, including Victoria Azarenka and Sloane Stephens.

She'll now face Swiss Timea Bacsinszky. The 23rd seed ousted Belgian outsider Alison Van Uytvanck in straight sets. Bacsinszky is having a breakthrough campaign, winning two titles and once owning a 15-match winning streak.
