Since 2004, the Grand Slams have been dominated by the Big Three, and the race for who will finish with the most majors has begun. Rafael Nadal is one Grand Slam away from tying Roger Federer's record of 20, a number that seemed like it would last forever. But Novak Djokovic is not far behind with 16; he's openly motivated to reach Federer's record.
All three are still alive in the Australian Open draw this year, with Federer taking on Djokovic in the semifinals, and Nadal about to face Dominic Thiem in the quarterfinals. There's no time like the present to ask: who will end their career with the most Grand Slams?
