Michael Te-pei Chang is an American former professional tennis player and coach. He is the youngest man in history to win a singles major, winning the 1989 French Open at 17 years and 109 days old. Chang won a total of 34 top-level professional singles titles, was a three-time major runner-up and reached a career-best ranking of world No. 2 in 1996.
