Tennis great Roger Federer has won 16 and counting Grand Slam titles. In this slideshow you will see the Grand Slams that have defined Federer's spectacular career.
Shocker. Upset. Stunner.
Whatever you call it, it is definitely one of those matches that people call the "passing of the torch."

The first time Roger Federer kissed a trophy was at Wimbledon in 2003, at only 21-years-old. He defeated Andy Roddick in the semifinals and in the final he beat Mark Philippoussis 7-6 6-2 7-6.
This Grand Slam not only marked Federer's first hard-court grand slam, but he also claimed the World No. 1 Ranking from Andy Roddick.

Roger Federer not only defended his title at Wimbledon 2004, but also started an unprecedented record of 23 straight grand slam semifinals.
Roger Federer defeated Lleyton Hewitt in one of the most lopsided finals in tennis history 6-0 7-6 6-0.
Federer was ranked No. 1, so how could Rafael Nadal trouble Federer?

For five years, Federer was the undisputed Lord of the Lawns. For 65 matches, he was never really challenged. It all came to an end against Rafael Nadal in 2008 when he lost the final, which was dubbed the "greatest match of all time." Nadal prevailed 6-4 6-4 6-7 6-7 9-7.
Federer was suffering from a relatively bad year, having not won a Major at the first three slams.

This was also Federer's fifth consecutive US Open title.
Federer had not won the Australian Open since 2007, but he was the favorite against rival Rafael Nadal, who was appearing in his first hard-court Grand Slam final.
After all, Nadal had outmuscled Fernando Verdasco in five hours, wouldn't he be exhausted?
It turned out that the answer was yes, but Nadal still had the energy to prevail against Roger Federer in a second consecutive five set match.
Rafael Nadal was out. Robin Soderling was in.
It was Soderling that Roger Federer was facing in the 2009 French Open title. He was only the man who beat Nadal at the French Open and he was standing in the way of Federer’s French Open title.
And Federer won it, which added to the irony.
Roger Federer couldn't beat Nadal at the French Open, but Robin Soderling could.
Federer could beat Soderling, but Nadal could not.
Federer became one of only six men to complete the Career Grand Slam.
Roger Federer was playing in front of tennis greats Bjorn Borg, Pete Sampras, and John McEnroe.

This defeat marked the first time in 22 years that two consecutive defending champions were beaten by the same person.
This ended Federer's 23 consecutive semifinals at grand slams and 8 consecutive major finals, as well as his quest to complete a Calendar Grand Slam, and his quest to break the record for holding the World No. 1 the most weeks. Federer came up one week short to equaling the record held by Pete Sampras.
