James Courier is an American former world No. 1 professional tennis player. As a junior player in the 1980s, Courier attended the Nick Bollettieri Tennis Academy and won the prestigious Orange Bowl in 1986 and 1987 (the first to win back-to-back titles since Björn Borg), as well as the French Open junior doubles title in 1987.
Courier turned professional in 1988 and made his Grand Slam breakthrough at the 1991 French Open when he defeated Stefan Edberg and Michael Stich to reach his first Grand Slam final. In the final he defeated his former Bollettieri Academy roommate Andre Agassi in five sets to win his first Slam. He made the quarterfinals of Wimbledon before losing to eventual champion Stich. At the US Open he defeated defending champion Pete Sampras in the quarterfinals and then Jimmy Connors in the semifinals, before losing the final to Edberg. He was the youngest man to reach the finals of all four Grand Slam singles tournaments, at the age of 22 years and 11 months. He also won five Masters 1000 series titles. Until Novak Djokovic in 2016, Courier was the last man to win the Australian and French Opens in the same calendar year.
Since 2005, he has been a commentator on the Australian Open for the host broadcaster, the Seven Network, and more recently the Nine Network. He has also served as an analyst for the Tennis Channel. In August 2019, Courier was working for Prime Video UK, for their exclusive coverage of the US Open.
