(CNN) — The seeds just can’t stop tumbling out of Wimbledon and on Monday it was the turn of world No.1 and five-time champion Serena Williams to experience that sinking feeling.

The American crashed out of the grass court grand slam in the last-16 following a shock defeat by Germany’s Sabine Lisicki — her first reverse in 34 matches.

Favorite for the title, Williams lost the opening set 6-2 before roaring back to level a pulsating contest by taking the second 6-1.

But Lisicki, seeded 23rd at the tournament, produced one of the greatest performances of her career, coming from a break down to take the final set 6-4 and send shockwaves through tennis.
