Rafael Nadal was sent crashing out of Wimbledon by dread-locked German qualifier Dustin Brown on Thursday, his fourth successive humiliation at the All England Club.
Nadal, the 2008 and 2010 champion, slumped to a 7-5, 3-6, 6-4, 6-4 second round defeat against the world number 102.
It was the 29-year-old's first ever defeat to a qualifier at a Grand Slam and came in the aftermath of losing his French Open crown where he had been champion nine times.
The loss followed his 2012 second round exit to world 100 Lukas Rosol, a first round beating by the 135-ranked Steve Darcis in 2013 and last year's fourth round defeat to Nick Kyrgios, who was at 144.
Down at his lowest ranking for a decade -- at 10 in the world -- Thursday's defeat was yet another symptom of the great Spaniard's game being in a terminal state of decline.
For Brown, who once drove to tournaments in a camper van to save money, it was his second win against Nadal having won on grass in Halle in 2014.
It also gave him a third round clash against Serbia's Viktor Troicki.
Nadal had the luxury of the first break for a 3-1 advantage in the opening set which was quickly cancelled out by Brown in the fifth game.

Normal service was resumed in the second set with the 14-time major winner breaking in the third and ninth games to level the contest.
But Brown was far from disheartened, continuing to attack at every opportunity, and he gained the crucial break in the fifth game of the third set against an increasingly bamboozled and error-plagued Nadal.
Sensing victory was there for the taking, the 30-year-old Brown broke in the first game of the fourth set courtesy of a wild, mis-hit Nadal backhand which sailed wide.
Nadal saved two match points in the ninth game of the fourth set but Brown sealed a memorable victory on his 13th ace.
