Young guns who can make it to the top

Stefanos Tsitsipas Age 20 Nationality Greek

World ranking 15 Grand-slam best Wimbledon 4R 2018 With his elegant shot-making and impressive athleticism, he is one of the most exciting players to watch on the tour. His stunning run to the Rogers Cup final in August while still only a teenager underlined his potential. Alexander Zverev Age 21 Nationality German

World ranking 4 Grand-slam best French Open QF 2018 For so long tipped as a future world No1, he started to make good on his reputation by winning last year’s seasonending ATP Finals. Still yet to deliver at the grand slams. Karen Khachanov Age 22 Nationality Russian

World ranking 11 Grand-slam best Wimbledon 4R 2018 and French Open 4R 2017, 2018 A thunderous serve and forehand mean he can blow anyone off the court when he is on song. One of many young Russians to look out for. Borna Coric Age 22 Nationality Croatian

World ranking 12 Grand-slam best US Open 4R 2018 Made major strides last year and ended up one of the alternates for the ATP Finals. Supremely fit and hard to break down from the baseline. Alex de Minaur Age 19 Nationality Australian

World ranking 31 Grand-slam best Wimbledon 3R 2018 and US Open 3R 2018 Mentored by Lleyton Hewitt, and cut from a similar cloth, he is even quicker around the court than his fellow Australian. De Minaur is playing more aggressively rather than relying on his phenomenal defence.
