Like many good badminton players of that time, Sidney Smith was a top-class tennis player, playing a total of 87 matches at Wimbledon in the men’s singles and doubles from 1893 to 1907. The year that he won the first All-England badminton men’s singles title in 1900 he also won the Wimbledon All-Comers men’s singles final but lost in the Challenge Rounds final.
Wimbledon until 1922 had a system where players would play in the All-Comers tournament, and then the winner would play in the Challenge Rounds final the holder of the title from the previous year, the winner of that final would be the Wimbledon champion.
In the men’s doubles at Wimbledon, Smith with Frank Riseley won the All-Comers final 1902, 1904, 1905 & 1906 and in 1902 & 1906 they won the Challenge Rounds final to be the Wimbledon’s Men’s Doubles Champion.
It tells us in Wimbledon: The Official History of the Championships “Sidney Smith- who, despite or perhaps because of a leg brace covered the court remarkably fast and wielded a forehand that was regarded as the fiercest in the game.”
