Just because a player is the top seed in his or her bracket doesn't mean they are guaranteed a spot in the quarters, let alone the semis or the finals.
Caroline Wozniacki already proved that.
But the flip side to that truism is the fact that lower seeds or even qualifiers and wild cards can make a serious run at the title.
And while there have been plenty of upsets and surprise contestants this year at Wimbledon here are the five who have—to use the terribly clichéd phrase—"shocked the world!"
No. 5: Bernard Tomic
An 18-year-old qualifier reaching the quarters—and giving the world's second ranked player, Novak Djojovic, a serious test when he got there—should always be somewhat surprising.
But because this kid looks like the "next big thing," it can't be too much of a stunner.
No. 4: Feliciano Lopez
Upsetting Andy Roddick was a big deal, but the 29-year-old, who has only two wins in his career, fought some great battles throughout the tourney, most notably coming back from a two-set deficit to topple Łukasz Kubot on his way to the quarters.
No. 3: Tsvetana Pironkova
Although the 23-year-old was retired in the quarterfinals by Petra Kvitová, she did battle hard, forcing a third set.
And just reaching the quarters being a 32-seed is a pretty impressive achievement. Oh, and so is defeating Venus Williams in the fourth, one round after taking down the world's second ranked player, Vera Zvonareva.
No. 2: Sabine Lisicki
Maria Sharapova and a TBA stand in the way, but if Lisicki becomes the first wild card to claim the Wimbledon crown would be a pretty special achievement. Either way it's been a remarkable run, highlighted by her taking down Marion Bartoli.
No. 1: Jo-Wilfried Tsonga
But for Tsonga to do so from the 12th seed and after trailing by two sets is historic.
