Ion Țiriac (; born 9 May 1939), also known as the "Brașov Bulldozer", is a Romanian businessman and former professional tennis and ice hockey player. He has been president of the Romanian Tennis Federation. A former singles top 10 player on the ATP Tour, Tiriac was the winner of one grand slam title, the 1970 French Open in men's doubles. Țiriac was the first man to play against a woman and defeat her, in a sanctioned tennis tournament (against Abigail Maynard, in 1975). The highlight of his ice hockey career was participating as defenseman in the Romanian national team at the 1964 Winter Olympics. After retirement, Tiriac became active as a tennis coach, advisor and player agent in the 1980s, taking under his wing Ilie Năstase, Manuel Orantes, Adriano Panatta, Guillermo Vilas, Henri Leconte and the young Boris Becker. Later, Țiriac developed the Mutua Madrid Open ATP masters tennis tournament, which he owns. In 2013, he was elected as contributor into the International Tennis Hall of Fame. He has been managing French tennis player Lucas Pouille since December 2016. As a tennis player, Tiriac played dramatic five-setters against Rod Laver, Stan Smith, Jan Kodeš and Manuel Orantes. His singles record includes wins over Arthur Ashe, Stan Smith, Roscoe Tanner, Manuel Orantes, Andrés Gimeno, Adriano Panatta and Niki Pilić. He played three Davis Cup finals (in 1969, 1971 and 1972). As of April 2022, Forbes ranked him as the third-richest person in Romania with a net worth of $1.6 billion. Sports career Țiriac was born in Transylvania, which is probably the reason why he has the nickname 'Count Dracula'. He first appeared on the international sports scene as a child ping pong champion, then subsequently as an ice hockey player on the Romanian national team at the 1964 Winter Olympics. Shortly after that he switched to tennis as his main sport. With fellow Romanian Ilie Năstase he won the men's doubles in the 1970 French Open and reached the Davis Cup finals several times in the 1970s. John McPhee wrote of him that his drooping mustache suggests "that this man has been to places most people do not imagine exist. He appears to be a panatela ad, a triple agent from Alexandria, a used-car salesman from central Marrakesh. Tiriac has the air of a man who is about to close a deal in a back room behind a back room." Țiriac
