(CNN) -- Andy Roddick has crashed out of the Australian Open in straight sets 6-3 6-4 6-4 to Swtizerland's Stanislas Wawrinka at the Rod Laver Arena in Melbourne.
The American was no match for the No.19 seed who hit an incredible 67 winners during their fourth round match.
"I played an unbelievable match and it was one of my best, for sure," Wawrinka said, AFP reported.
"To beat Roddick in three sets, it's really good for me. I am very happy with my game tonight." he said.
Wawrinka broke Roddick's serve three times, while he only faced three break points on his own.
It was only Roddick's second straight sets defeat at Melbourne Park -- Roger Federer outplayed him in their semi-finals meeting two years ago.
The No.8 seed said he thought the cooler conditions on Sunday night hadn't helped his cause.
"I wasn't able to get the ball to jump much, so a lot of the shots he hit were in his pocket and I was having a hard time getting it out of that zone," Roddick said, AFP reported.
The victory sets up an all Swiss quarter-final -- a first in the Open era -- as Wawrinka takes on defending champion Roger Federer for a place in the last four.
Wawrinka's last grand slam meeting with Federer came in the fourth round at the French Open last year. The World No.2 won that match in straight sets and has beaten his compatriot six times in seven previous meetings.
Earlier, Federer made it to his 27th consecutive grand slam quarter final -- a feat which equals Jimmy Connors record -- after overcoming Spain's Tommy Robredo in four sets 6-3 3-6 6-3 6-2.
Third seed Novak Djokovic made lighter work of his Spanish opposition, beating 14th seed Nicolas Almagro 6-3 6-4 6-0 to book his place in the quarter-finals.
Sixth seed Tomas Berdych also recorded a straight sets victory over ninth seed Fernando Verdasco 6-4 6-2 6-3 to secure his passage into the last eight.
