Some of the bigger names have also warmed the hearts, with Venus Williams, Roger Federer and Rafael Nadal all rolling back the years to delight fans who feared their best days were behind them.
But perhaps the greatest tale of all has been the remarkable renaissance of Croatia’s Mirjana Lucic-Baroni, who has battled her way to the Australian Open semi-final at the age of 34, 19 years after her previous match win at the tournament, and 18 years since her only other grand slam semi.
I'm so happy for you,Mirjana!
What a journey, you deserve all the success!Good luck in your @AustralianOpen semifinal,half italian girl!😊😊 pic.twitter.com/TpulrQ3ZMa— Roberta Vinci (@roberta_vinci) January 25, 2017
