Serena out! Five of the biggest shocks in women's tennis history

After Serena Williams was dumped out of the US Open by unseeded Italian Roberta Vinci, we look back at five of the biggest upsets in the history of women's tennis.

Navratilova v Horvath - 1983 French Open, 4th round

Martina Navratilova seemed untouchable as the world's best player, winning three of previous four majors and all 36 of her matches in 1983, as she headed into the 4th round of the French Open. America's Kathleen Horvath was her opponent, a player ranked 45th in the world. Horvath had reached the 4th round of a major for the first time, but her lack of big-stage experience proved no issue as she Navratilova with a 6-4 0-6 6-3 victory. 

Graf v McNeil - 1994 Wimbledon, 1st round

Steffi Graf was in similarly dominant form as she headed into the defence of her Wimbledon title back in 1994, having won four of the last five majors. But what should have been a routine win over American Lori McNeil turned into a history-making 7-5 7-6 defeat, as Graf became the first female champion in the history of Wimbledon to surrender their crown in the opening round.

Hingis v Majoli - 1997 French Open final

Croatia's Iva Majoli became the lowest-seeded female player to win an Open era Grand Slam when she defeated Martina Hingis in the 1997 French Open final. Hingis would go on to win the other three majors that year but could not find an answer to ninth seed Majoli, who beat the Swiss 6-4 6-2.

Williams v Sharapova - 2004 Wimbledon final

Serena Williams was already a two-time Wimbledon winner and defending champion when she encountered a 17-year-old Maria Sharapova on Centre Court. Williams was expected to claim her third consecutive Wimbledon title but was instead blown away by the young Russian in a 6-1 6-4 victory that announced Sharapova's arrival on the world tennis stage. 

Williams v Razzano - 2012 French Open, 1st round

It was Williams who again fell victim to a huge Grand Slam upset, in what remains her only 1st round defeat at a major. Virginie Razzano, the world No 111, was a set and 5-1 down in the tie-break when she produced a stunning comeback. After winning the tie-break 7-5 to take the match to a decider, she won the first five games of the third set to record a 4-6 7-6 6-3 win in a match that lasted more than three hours.
