Roger Federer possesses many, many ATP records.

Because he is the man many consider the GOAT (greatest of all time), that fact should surprise no one who has been following tennis since Federer began his assault on the record books.

Turning pro in 1998, Federer announced his arrival at the top of the men's game in February of 2004, when he captured the No. 1 ranking for the first time.

From 2004 through 2007 Federer dominated, often winning three Grand Slams in a season. He held the No. 1 ranking a record 237 consecutive weeks.

But after winning Slam No. 16 at the Australian Open in 2010, Federer's pace slowed considerably.

Of late, however, Federer has once again been advancing upon long-held tennis records—those many believed safely chiseled in stone for the ages.

Federer has lost only two matches in 2012—to Rafael Nadal in the 2012 Australian Open semifinals and to John Isner in a five-set Davis Cup match in Switzerland. The world No. 3 stands at 22-2, entering this week's Sony Ericsson Open having just won his last three tournaments: Rotterdam, Dubai and most recently Indian Wells.

But no one individual can own all tennis records, right?
