(CBS News) It was a stunning women's singles final at the U.S. Open in New York Sunday. All the experts thought Serena Williams would crush Samantha Stosur of Australia. But instead, Williams blew her cool after an umpire's decision and Stosur took the trophy with a straight-set victory, 6-2, 6-3.
On "The Early Show" Monday, Stosur called her win "surreal."
As for the incident with Williams, Stosur said she just wanted to get past it and continue playing.
After a hard return to Stostur in the second set, Williams shouted "Come on," before Stosur had a chance to hit the ball -- a illegal action because it had the potential to distract her opponent. Williams lost the point.
Williams, who has had words with U.S. Open officials in years past, approached the umpire and said, "Aren't you the one who screwed me over the last time I was here? You have it out for me?" Williams added, "I promise you that's not cool. That's totally not cool."
When asked if her play was interrupted by Williams' screamed remark, Stosur said, "Everything was happening so fast. I was just trying to get the ball and before I knew it, then there was all of that commotion up at the net. I just tried to think about what I was doing for the next point and get on with it, really."
"Early Show" co-anchor Jeff Glor remarked, "You were remarkably well-composed, and everyone is talking about how confident you looked."
So was she nervous during the match?
"Oh, there were definitely some nerves," Stosur said. "But I think I felt just in-control pretty much from the first point, so I think that really helped settled me down. And then, right at the end, I could feel my heart pounding out of my chest and tried to keep it together and think about the next point."
Stosur has beaten Williams before. She defeated her in the quarterfinal of the French Open in 2010.
But Stosur said this was a whole different experience.
She said, "You can play someone like Serena on any court in the world, but that probably is the biggest court we get to play on and the biggest moment of my career. So, to achieve what I did under those circumstances, I'm just really proud of myself, I guess."
As for those circumstances, particularly following the situation with Williams and the umpire, Stosur said, "It was pretty difficult going around that change of events to serve the next point and the crowd was going nuts, and it was so loud and I felt like the noise was going right through me. I just wanted to get that next ball in the court and try and settle everyone down and get on with it."
Stosur is the first Australian woman to win a major tournament in 31 years.
She said about going home later this week, "I'm sure the reception will be amazing. I can't wait to get back there, but I'm sure it's absolutely going to blow my mind. "
