7. Margaret Court

In purely numbers terms, the legendary Australian Margaret Court cannot be beaten in the pantheon of great comebacks.

Having retired from tennis aged 24 after winning Wimbledon in 1966 - her 13th grand slam - Court moved back home to Australia to marry her husband Barry, supposedly never to return to the sport.

Two years later however, Court was back competing and after winning Wimbledon and Australian Open titles in 1969, she pulled off the unfathomable feat of a calendar Grand Slam the following year.
