The Belgian outsider who knocked Rafael Nadal out of Wimbledon said he took advantage of the Spaniard's rusty display to produce a shock result.
Steve Darcis, ranked 135 in the world, said: "Nobody was expecting my win today. Rafa didn't play his best tennis, but I knew the first match on grass is always difficult.
"I tried to do what I like to do, come to the net as soon as I can, not play too far from the baseline. I don't know what to say right now, I'm really happy."
Two-time champion Rafael Nadal has been knocked out of Wimbledon by Belgium's Steve Darcis in one of the biggest shocks of recent years.
Darcis, ranked 135 in the world, beat the Spaniard 7-6 7-6 6-4 in their first round match on Court One.
Nadal, who won the French Open earlier this month, also suffered a shock early elimination at Wimbledon last year when he lost to Lukas Rosol.
The 12-time Grand Slam winner, who was seeded fifth for this year's tournament, could have faced Roger Federer in the quarter-finals and Andy Murray in the last four.
Andy Murray was confirmed as the second seed for the Wimbledon men's singles today and French Open champion Rafael Nadal is a potential quarter-final opponent.
Nadal is still climbing back up the world rankings after a long spell out with a knee injury and fellow Spaniard David Ferrer gets the fourth seed spot.
It means that the French Open champion could play Murray, Novak Djokovic or Roger Federer as early as the quarter-finals.
And Andy Murray could face an unusually tough route of a Nadal quarter-final, Federer (world number 3) in the semi-final and Djokovic (world number 1) in the final.
