Serena Williams won the Australian Open for a seventh time last month, passing Steffi Graf for the most Grand Slam singles titles in the Open era with 23.
Prior to her title in Melbourne, many considered Serena to be the greatest female tennis player of all time. Upon setting the record, the majority of fans and pundits argued that she firmly cemented her status as the unequivocal best.
Andy Roddick, the former U.S. Open champion who has known Williams since they were children, took it a step further. He believes that the American’s accomplishments transcend tennis.
