Louk Sorensen won in four sets at the Australian Open
Ireland earned their first Grand Slam singles win in the Open Era as Louk Sorensen beat Taiwan's Lu Yen-Hsun 6-4 3-6 6-2 6-1 at the Australian Open.
Sorensen, 25, had already done what no other Irish tennis player had managed since Matt Doyle back in 1985 when he made it through the qualifying event.
"I do not know what is going on right now. I have suddenly got so many friend requests on Facebook," he said.
"I am feeling great, it is the biggest achievement of my career so far."
Before Tuesday's breakthrough win, Sorensen was best known as the son of Sean Sorensen, the current captain of the Ireland Davis Cup team, who played in the first round of Wimbledon in 1977, losing to Rod Laver.
Louk was raised in Germany and although his parents now live in Dublin, Sorensen remains in Stuttgart, training and playing in the German tennis league's third division.
"The money's good," he said. "And I can be the number one player [in Ireland]."
Sorensen has won tournaments on the Challenger and Futures Circuit but had to go through the qualifying competition for the Australian Open because his ranking of 284 was too low for an automatic place.
He is the first man from the Republic of Ireland to reach the main draw of a Grand Slam since Doyle lost in the first round in Melbourne in 1985.
Sorensen's second-round match is against American 33rd seed John Isner, who won last week's Auckland International, and will present a whole new challenge for the Irishman.
"I think it was an advantage to come through the qualifiers because I was used to the courts.
"The level between the qualies and the main draw, there is not such a big difference. You just need a bit of luck."
