Watch back the moment American Sofia Kenin won her first Grand Slam title at the 2020 Australian Open in Melbourne. It was a stunning moment as the 14th seed soared to the triumph, rallying from a set down to defeat former world number one Garbine Muguruza, 4-6, 6-2, 6-2. She became the youngest American since Serena Williams in 2002 to win a Grand Slam title.
