No 1: Wimbledon 2003
bt Mark Philippoussis 7-6 (7-5) 6-2 7-6 (7-3)
Roger Federer began Wimbledon 2003 with a big question mark hanging over him. Would he ever find the consistency to win the Grand Slam title his myriad talents deserved?
The pony-tailed Swiss answered in magnificent fashion, crushing Andy Roddick in the semi-finals before ending the surprise resurgence of Mark Philippoussis in the final. After lifting the trophy, he famously sobbed as he was interviewed on Centre Court by the BBC's Sue Barker.
No 2: Australian Open 2004
bt Marat Safin 7-6 6-4 6-2
A semi-final win over Juan Carlos Ferrero saw Roger Federer topple Andy Roddick and become world number one for the first time. It was the start of a record 237-week reign which ended on 18 August 2008.
He fully justified his status as the world's best player with a commanding display against Safin, who had equalled the record for the number of sets played at a Grand Slam during the tournament.
"To win the Australian Open and become number one in the world is a dream come true," he said.
No 3: Wimbledon 2004
bt Andy Roddick 4-6 7-5 7-6 (7-3) 6-4
Roger Federer successfully defended his Wimbledon title but not without a fight as Andy Roddick attempted to avenge his semi-final defeat of the previous year.
The Swiss benefited from two rain delays after falling a break behind at one set all, coming out to break back and dominate the tie-break.
Roddick forced six more break points in the fourth set but could not covert and Federer took the win to maintain his 100% record in Grand Slams final. More tears followed as he told the BBC's Sue Barker, "I got lucky today for sure."
No 4: US Open 2004
bt Lleyton Hewitt 6-0 7-6 (7-3) 6-0
A magnificent year for Roger Federer was capped with a first US Open title at Flushing Meadows in New York, making him the first man since Mats Wilander in 1988 to win three Grand Slam titles in a year.
Former champion Hewitt arrived in the final on a 16-match winning streak but was blown away by Federer at his absolute best.
The world number one swept through a magnificent opening set to love in just 18 minutes and, after a valiant effort from Hewitt in the second, Federer repeated the trick in the third set.
