MELBOURNE, Australia — When Rod Laver beat Roy Emerson to win the Australian Open title in 1962, the event was played on grass in Sydney and, as an amateur, he took home no prize money.

Much has changed in tennis since Laver's victory 50 years ago, but one thing has remained the same. No other man has been able to match his feat — winning all four majors in the same calendar year.

The Australian tennis great didn't just win the Grand Slam once; he replicated the feat seven years later as a professional after the Open Era began and professionals were again permitted to enter the majors.

The 73-year-old Laver said Wednesday in a visit to Melbourne Park that he was "honored to be able to pull it off."
