Andy Roddick thinks he proved that Roger Federer was not invincible despite losing the Wimbledon final to the Swiss master on Sunday.

"All is not lost because I lost today," Roddick said after his 4-6, 7-5, 7-6, 6-4 defeat. "I still had a hell of a run and I proved that Roger's not quite invincible. He's pretty close but not quite.

"He definitely has an aura about him, he's an unbelievable player and people know that. I don't think anyone's going to argue with that."

The American, ranked number two in the world, has now lost six of his seven meetings with Federer, the world number one.

Twelve months ago the pair met in the semis and Federer was in irresistible form as he dished out a 7-6 6-3 6-3 masterclass in grasscourt tennis to the American.

In Sunday's final, Roddick came out firing his thunderbolt serves but Federer found a way to draw the sting before weaving his own magic on Centre Court and securing his second successive Wimbledon crown.

"The thing with Roger is that he just makes it look easy," Roddick said. "He can make nothing out of something and he's unparalleled in doing that and keep himself alive in points."

"I'm winning matches, just not against him. Couple of years ago, when we played our first three matches, he was a lot better than me.

"I felt today was a step in the right direction. I have a lot I can improve on and I need to focus on that. He's a spectacular player so I can't really worry about what he's doing."

Roddick felt he had chances in the two hour 30 minute contest, especially in the fourth set when he earned six break points.

But each time Federer ended up frustrating the U.S. Open champion.

"I went out and tried to take it to him, I was successful most of the time but a couple of points I wasn't and that was the key," said Roddick. "It's tough when you knock enough times and no one answers. He just came up with the goods.

"He's always on an even keel and doesn't give you the pleasure of knowing you're on top of him.

"I gave all the effort I had out there today. I played with a lot of heart and came out short."
