Tim Henman

Five men to watch

John Isner

Age 33 Wimbledon best

Third round (2014, 2015, 2016)

Nationality

American

Seeding 9 Titles 13 tour titles, 0 slams The players who used to frighten me were the big servers. If Isner (below) gets on a roll with his serve he is a nightmare to play against.

Kevin Anderson

Age 32 Wimbledon

best Fourth round (2014, 2015, 2017)

Nationality

South African

Seeding 8

Titles 4 tour titles, 0 slams Has made huge improvements, and when he is serving well, getting anything on the return is hard.

Milos Raonic

Age 27 Wimbledon best Final (2016)

Nationality Canadian

Seeding 13

Titles 8 tour titles, 0 slams His ranking has dropped but no one will want to play him. Raonic (above) has a solid serve and is a better volleyer than a lot of the others.

Nick Kyrgios

Age 23 Wimbledon best

Quarter-final (2014)

Nationality

Australian

Seeding 15 Titles 4 tour titles, 0 slams He probably has more ability than anyone outside the “Big Four”. But the physical and mental aspects are where Kyrgios (left) lets himself down. Hopefully he can become more reliable in those areas and then we will see better results.

Denis Shapovalov

Age 19 Wimbledon best First round (2017)

Nationality

Canadian Seeding 26

Titles 0

A huge star of the future. He has great variation with that leftie one-handed backhand. He can change the pace and he is a real shot-maker.
