Badminton tournament
The 1958 Thomas Cup competition is an international team tournament for supremacy in men's badminton (its female counterpart is the Uber Cup). Beginning in 1948–49 it was held every three years until 1982 and has been held every two years thereafter. Nineteen teams contested for the Thomas Cup during the 1957-1958 season. As defending champion Malaya (now Malaysia) was exempt until the conclusive tie (team match) called the challenge round. The other eighteen teams were divided into four qualifying zones; Asia, Australasia, Europe, and Pan America; with the winners of each intra-zone competition advancing to inter-zone competition in Singapore to determine a challenger to Malaya.
