Ion Țiriac – $1.28 Billion
Romanian professional tennis and hockey player Ion Țiriac has quite an impressive net worth. Although tennis was his main sport, he was also a great hockey player, a member of team Romania in the 1964 Winter Olympics. Interestingly enough, Ion was the first male player to ever have a match against a woman in a sanctioned tournament. He was once a top 10 player and won the 1970 French Open in men’s doubles. Țiriac became notorious after retirement, becoming the owner and developer of the Mutua Madrid Open Tennis Tournament and a contributor to the International Tennis Hall of Fame. Ion currently has a net worth of $1.28 billion.
