Tennis: Stefanos Tsitsipas reaches the semi-finals of Australian Open

Stefanos Tsitsipas followed up on his stunning upset of Roger Federer by becoming the youngest man to reach a Grand Slam semifinal since 2007 when he beat Roberto Bautista Agut 7-5, 4-6, 6-4, 7-6 at the Australian Open. Tsitsipas is the first player from Greece to reach the semifinals of a Grand Slam, and at 20 years, 168 days, is the youngest man to make the semifinals at a major since Novak Djokovic at the 2007 U.S. Open. He's the youngest man to do so in Australia since Andy Roddick in 2003
