Nadal-Federer, Federer-Nadal.
To the delight of tennis fans, the Australian Open final on Sunday will match two of the all-time greats, 35-year-old Roger Federer and 30-year-old Rafael Nadal. It is their first meeting in a Grand Slam final in more than five years. The excitement has been amplified by the unexpectedness of the matchup. Both players are coming off long layoffs because of injuries and have fallen in the rankings. Nadal is seeded ninth in Melbourne, and Federer 17th.
