LONDON, (Reuters) – Roger Federer and Serena Williams  were named 2009 ITF World Champions yesterday after capturing  four grand slam singles titles between them in 2009.

It is the fifth time Switzerland’s world number one Federer  has won the ITF award, based on performances at grand slam  events, Tour events, Davis Cup and Fed Cup.

Williams took the award for the second time despite her  foul-mouthed outburst at a line judge at this year’s U.S. Open.

Williams was fined $175,000 and put on probation for two  years by the Grand Slam Committee following the tirade that  resulted in her receiving a point penalty and losing her  semi-final against Kim Clijsters.

Federer had no such shadow hanging over his season.

“It is an honour for me to be named ITF World Champion for a  fifth time,” Federer said in an ITF statement. “It was an  incredible year for me both on and off the court.

“To win my first Roland Garros title, break the all-time  Grand Slam record and regain the No. 1 ranking is amazing. It  means a lot to me to finish the year again at the top.”

Federer took his grand slam haul to 15 with his titles at  Roland Garros and Wimbledon. Williams, who captured the world  number one spot at the season finale in Doha, has 11 singles  majors after winning the Australian Open and Wimbledon.

Serena and sister Venus were named women’s doubles World  Champions for the first time with Bob and Mike Bryan taking the  men’s doubles honour for a record sixth time.

“This has been another memorable year for tennis, with some  outstanding performances by our World Champions. Roger Federer  has truly earned his place in the history books, while the  Williams sisters remain the strongest competitors on the women’s  tour,” ITF president Francesco Ricci Bitti said.
