Maria Sharapova has claimed her Wimbledon defeat to Sabine Lisicki proves that no-one on the tour is bulletproof.
The top seed, fresh from winning the French Open, looked in fine touch throughout last week and seemed to be warming to the challenge of landing a second Wimbledon title.
But while her enthusiasm never cooled, she was beaten in straight sets by the heavy-hitting German on a damp and drizzly Court One.
Her loss does not carry the same weight as Rafael Nadal's defeat to Lukas Rosol last week - Lisicki is seeded 15th and not, like Rosol, ranked at 100th in the world.
And the 25-year-old Russian conceded afterwards that no-one is safe from defeat, no matter their ranking or reputation.
"I don't think it's a lesson for the players, I think it's a lesson for the storylines," she said when asked about the shocks happening in 2012.
"We never really underestimate any opponent. If people are to be considered favourites for matches and tournaments, we will have these storylines.
"The reason we start at the first round is so you have to go through all those opponents to get to the final stage of a tournament, whether it's a grand slam or the middle of nowhere. That's the reason why we go out and play.
"It could be the number one seed against someone who has come out of the woods. It doesn't matter, you still have to play and win. On any given day, there can be an upset. That's the sport and that's why we watch."
Sharapova rarely looked like winning at any point, and was eventually condemned to a 6-4 6-3 reverse.
