Roddick went through the entire week without dropping his serve

Roddick went through the entire week without dropping his serve, and did not face a break point in the final.

"This is as well as I have ever played. With these great players, to finish a week like this is just great," he said.

Roddick claimed the scalps of world number two Rafael Nadal and Novak Djokovic en route to the final.

He earned his 25th career title and his second of the year after winning in San Jose last month.

It was all the more remarkable because Roddick had a 6,000-mile journey from Memphis via Frankfurt which left him exhausted for the first two days of the tournament.

"I was, like, asleep before I played my first match," he said.

"Asleep on the players' lounge floor, with people stepping over me and Djokovic dropping stuff on me. I was pretty tired.

"I didn't know what to expect. So maybe that's why I played well. Tennis can be like that."

The American was also playing for the first time since splitting from coach Jimmy Connors.

The first set went with serve (Lopez delivered 24 aces in all) but Roddick took a 4-1 lead in the tie-break before allowing the Spaniard back in.

When Lopez thundered three aces in a row to nose ahead 4-3 in the second set an upset seemed possible, but Roddick pounced on an error to turn the pressure around.

"I didn't feel like he was missing at all in the first set," Roddick added.

"When I lost the tie-break I told myself just keep at it because I don't remember him missing a ball."
