Roger Federer captured his seventh title of the year at the Swiss Open on Sunday - but the Wimbledon champion's high standards meant he was frustrated by dropping a set to promising Russian Igor Andreev.

The world number one came to his native Switzerland immediately after winning his second consecutive Wimbledon crown and had complained of feeling jaded during recent days.

However, Federer displayed few signs of fatigue against Andreev as he posted a 6-2 6-3 5-7 6-3 triumph.

"I'm tired in general, I knew my game wouldn't be as consistent as if I would have been totally fit," said Federer.

"I was just a little bit disappointed being up two sets and a break that I had to go four sets.

"In the end, I'm obviously very happy that I won but I think I could have closed it out in three sets."

Federer held a 4-2 lead in the third set but Andreev, playing in his first ATP final, won six of the next seven games to give the home crowd slight cause for concern.

However, Federer left no doubt in the fourth set to extend his winning streak to 16 matches.

It is the 22-year-old Federer's first career title in Switzerland, having lost his three previous finals on home soil.

He joined Rod Laver (1962) and John Newcombe (1971) as the only players to win Wimbledon and Gstaad in the same year.

"For me, it is a dream come true," Federer said.

"Finally, I won a title in Switzerland after four times in the final. I never thought I would win this tournament. There was a lot of talk about this for a long time."

In addition to Wimbledon, Federer also won the Australian Open in January as well as titles in Dubai, Halle, Hamburg and Indian Wells.

Andreev, who turns 21 on Wednesday, saw off second seed Rainer Schuettler on his way to the final.

"It was an unbelievable week, I'm very happy with my tennis," he said.

"It's a good experience for me for the future. I just have to learn from the mistakes I did today and not making them in the future.

"This is my best tournament, it's going to stay with me for all my life."
