Mike Sangster made his first Wimbledon appearance aged 17 in 1958 and quickly rose to become British No.

In 1961, Sangster became the first Briton in almost a quarter of a century to reach the Wimbledon Men's Singles Semi-finals (the previous being Bunny Austin in 1938).

The only other Britons to have reached the Wimbledon semis since have been Roger Taylor, Tim Henman and Andy Murray.

[5] In 1963, aged 22, Sangster reached the semi-finals of the French Tennis Championships where he lost to eventual champion Roy Emerson 8–6 6–3 6–4.

While Sangster never reached a Grand Slam final, he is one of only three British men since Fred Perry (the others being Tim Henman and Andy Murray) to have reached the semi-finals of three different Grand Slam events – Wimbledon in 1961, the US National Tennis Championships in 1961 and the French Championships in 1963.

This compares with the current world record of 155 mph set by Andy Roddick in a Davis Cup match against Russia in 2004.
