Jannik Sinner is well on his way to breaking some records. And there is no doubt that his name will quickly join those of the greatest of his sport in the history books. The Italian did not wait long since his victory over Nicolas Jarry (7-6 [2]7-6 [5]6-1) in the first round of the Australian Open makes him the fourth player to win 15 straight matches in a hard-court Grand Slam tournament. Before him, only Andre Agassi, Roger Federer and Novak Djokovic had achieved it.
