Roger Federer, what a legend, honestly I don't think tennis has ever seen someone so dominant in the last two or so decades.
Here are some Federer facts:
 Singles championships
- Federer has won 15 Grand Slam titles, breaking the previous all-time male record of 14 by Pete Sampras. Federer won 15 majors in a span of 25 majors, while Sampras won 14 in 45 majors.
It only took Federer 25 Grand Slams to break Sampras' record of 14. 15 titles in 25 majors, not a bad record and I can see theres more to come.
- Federer won five consecutive men's titles at Wimbledon from 2003–07, matching a feat achieved only by Björn Borg in the open era. William Renshaw won a male record six consecutive Wimbledon titles before the open era.
Federer winning 5 consecutive mens titles at Wimbledon is an amazing feat.
The open Era started in 1968, so in all Federer holds the record for most consecutive mens titles in the Open Era alongside Borg, even though Renshaw holds the actual record which was before the Open Era began.
Renshaw won Wimbledon from 1881 to 1886 and again in 1889.
- Federer has won six Wimbledon titles (2003-07, 09), second only to Sampras and Renshaw's seven Wimbledon titles.
I can see Federer possibly matching Sampras and Renshaws' seven Wimbledon titles this year, he would've made it if he defeated Nadal in Wimbledon 2008, but unfortunately that never came to be.
- Federer holds the open era record for most consecutive US Open titles at five (2004–08). Richard Sears(1881-87 US Open) and Bill Tilden (1920-25 US Open) won seven and six consecutive titles respectively before the open era.
Another record held by Federer, even though before the "open era" that Sears and Tilden were before him, Federer holds the record for most consectuive in the "open era".
- Federer, Pete Sampras, and Jimmy Connors have won a male open era record five US Open titles. Richard Sears, Bill Larned and Bill Tilden won 7 US Open titles prior to the open era.
I can see Federer surpass Sampras and Connors, as for Sears, Larned and Tilden it is possible if he can continue for another 5 or so years and keeps winning, but the older you get, the harder it may become.
