MELBOURNE - Rod Laver on Friday urged Novak Djokovic to go all-out for the calendar-year Grand Slam -- a feat not achieved in men's tennis since the Australian legend last won it in 1969. The 77-year-old Laver, who won all four major titles in the same year twice in his career, said Djokovic was ‘well on his way’ to the Grand Slam after he fell just one win short last year. The Serbian reached his fifth major final in a row late on Thursday when he destroyed Roger Federer in the Australian Open semi-finals. "I think it's good for the sport if someone does win a Grand Slam. This is not a club that (only) I'm a member of. It's an open course," Laver said. Laver said Djokovic ‘played beautifully’ in his opening two sets against Federer, which he wrapped up in 54 minutes for the loss of just three games.
