While history will record Roger Federer as the most successful player of all time, his reign arguably overshadowed the feats of another whose career reached a crescendo in 2007.
At a time when big bodies equalled big results in women's tennis, Belgium's pint-sized dynamo Justine Henin notched up a remarkable ninth grand slam singles title.
After pulling out of the Australian Open to deal with the break-up of her marriage, Henin would go on to win two of the year's three remaining majors.
But if Henin was being feted for her achievements, Martina Hingis' decorated career ended in controversy.
The 'Swiss Miss' revealed in November that she had tested positive to cocaine during Wimbledon and was retiring immediately.
But she maintained her innocence, saying she was quitting because of injury and the time it would take to clear her name.
