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 has owned from 2009 to 2021. 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 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 participated in the short period during the 1970s when women participated in established men's tennis tournaments. In his first match he defeated Abigail Maynard 6–0, 6–0 in their round one match at USTA pro circuit's Fairfiled County International Tennis Championship. It was the first time ever a female had entered a men's tournament.

After his retirement, he served as coach and manager for players such as Ilie Năstase, Guillermo Vilas, Mary Joe Fernández, Goran Ivanišević and Marat Safin. He became the sports agent of Boris Becker and managed his career from 1984 to 1993.

Țiriac was president of the Romanian Olympic and Sports Committee from 1998 to 2004.

Țiriac ran major men's events in Germany, including the season-ending championships in Hanover. Although tennis is now a much smaller part of his portfolio and occupies only 5 percent of his time, he has taken particular pleasure and pride in making Madrid Tennis Open a combined men's and women's event with €7.2 million in total prize money. The trophy awarded to the tournament winner bears his name.

Țiriac also held the license for the BRD Năstase Țiriac Trophy tennis tournament since 1996, until its last edition in 2016, before the tournament being relocated to Budapest.

In 2012, Țiriac was nominated for the International Tennis Hall of Fame in the contributor category.

On 13 July 2013, Țiriac joined the International Tennis Hall of Fame as a successful promoter and tournament director for numerous events including the two of the largest Masters 1000 events, the Italian Open and the Madrid Masters.

Business career

After his retirement as a professional tennis player, Țiriac became a businessman in (then West) Germany. In 1987, he appeared in a TV commercial for Miller Lite beer with Bob Uecker, who extols Țiriac's supposed humorous qualities, laughing hysterically while Țiriac sits stone-faced. (In reality, Țiriac was popular and outgoing, especially when he served as player/coach of the Boston Lobsters of World Team Tennis in the 1970s.)

In Germany, Țiriac met another Romanian businessman, Dan Petrescu. Țiriac and Petrescu became economic partners and collaborated in the development of several companies in the following years.
