Iván Balás was a Yugoslavtennis player of Hungarian ethnicity. He was the one of the first to play for the Yugoslavian team at the International Lawn Tennis Challenge, and later the Davis Cup in 1927. Technically his match was the second rubber of the tie. Apart from team competitions, he clinched international championships for Yugoslavia, Hungary, Austria, Romania and Slovakia in various events.
In college Balás played tennis as well as basketball, hockey, football and athletics. He began to win club and international tournaments in Nagybecskerek. Balás' first public triumph was recorded in 1922 in the men's singles of the National Championship in Novi Sad. At the 1924 Olympics in Paris, he played both singles in doubles. In the men's singles, he was defeated in the first round by Jack Nielsen. And in doubles, he and Đorđe Dunđerski advanced to the second roundbut lost to Jacques Brugnon/Henri Cochet. In 1926, he was crowned the champion of Yugoslavia. He was drafted into the Kingdom of Yugoslavia Davis Cup team for the first-ever Davis Cup match against India in Zagreb in May 1927, joined by Đorđe Dunđerski. Although they didn't win a game or set, both of them provided strong resistance. Balás even had two balls to have a chance to serve out the first set in the match against Hassan-Ali Fyzee, but did not succeed, as the Indian player came back to claim the match. On the third ball, the game was suspended due to bad weather, and so the match was decided after the first two days' results. The organizers agreed not to wait on Monday but to pass the remaining two dead rubbers and the victory to India. Balás next represented Hungary, debuting in a match against Austria. At the time he was fifth/sixth on the Hungarian rankings. In 1930 he earned the second place in mixed doubles at the Bucharest International Championship In Cluj-Napoca he lifted the doubles trophy with partner Béla Kehrling, defeating Romanian champion Constantin Cantacuzino and Alexandru Botez; he also finished third in singles and mixed contest. In 1931 he reached four doubles finals, including the Hungarian Covered Courts tournament mixed and men's doubles, and the Warsaw International Championships doubles and mixed doubles.
