Rusedski was born in Canada to a British mother and a German-born father of Polish-Ukrainian descent. He was a very promising junior player in Canada in the 1980s and subsequently caused some anger in Canada when he decided to adopt British citizenship and play for Britain in 1995. Rusedski has been with partner Lucy Connor for 15 years; they married in a Roman Catholic ceremony at Douai Abbey in England in 1999. Together they have a daughter, Scarlett Mary, born January 27, 2006.
Rusedski's highest ranking on the ATP was World Number 4.
Rusedski reached the singles final of the U.S. Open in 1997, where he lost to Pat Rafter in four sets, (shortly thereafter reaching his career high rank of World No. 4). He also won the BBC Sports Personality of the Year Award. Throughout the very successful 1997/8 period he was coached by Tony Pickard.
In 1998, Tim Henman eclipsed Rusedski as Britain's number one tennis player. Rusedski, however, won the Grand Slam Cup in 1999.
Rusedski was defeated in the second round of Wimbledon in 2005 by Joachim Johansson of Sweden 7–6(10), 3–6, 6–4, 7–6(5). Following that disappointment, Rusedski had a successful July. He successfully defended his title at the Hall of Fame Championship, defeating Vince Spadea in the final. This was the first time he had successfully defended a title and the third time he had won the championship. He then reached the semifinals at both the RCA Championships in Indianapolis, losing to Taylor Dent, and the Canada Masters tournament in Montreal, losing to Andre Agassi.
Towards the end of 2005, Rusedski's ranking had risen to the high thirties. A poor end to the year by Henman almost allowed Rusedski to overtake him as British number one again. But a defeat for Rusedski in the first round of the Challenger Event in Dnepropetrovsk, Ukraine, left him ranked 38th, just one place short of regaining the British top spot. Rusedski finally reclaimed the British number one spot on May 15, 2006, overtaking Andy Murray by getting to the third round of the Rome Masters Event. But Rusedski lost the top British ranking after a first round exit at Wimbledon.
On April 7, 2007, Rusedski officially retired from tennis after partnering Jamie Murray to a doubles victory over the Netherlands in a Davis Cup match, a result which gave Great Britain a winning 3–0 lead in the tie. He announced his retirement immediately after the win, during a live interview with Sue Barker on BBC Television. Rusdeski plans to stay involved with professional tennis in his retirement, and has expressed an interest in working with the Davis Cup team and British junior players. Rusedski held the record for fastest serve at 149 miles per hour until Andy Roddick broke it.
Rusedski won more singles titles than compatriot Tim Henman, with 15 singles titles compared to Henman's 11. Neither Rusedski nor Henman ever reached the quarterfinals of the Australian Open. Henman reached the semifinals of the French Open while Rusedski never made it past the fourth round at that tournament. Rusedski reached the final of the US Open while Henman never made it past the semifinals.
Rusedski has often been overshadowed in the press by the more popular Henman, especially at Wimbledon.
Rusedski's career has featured some controversies. His temper has got him into trouble on several occasions. For example, at the 1999 U.S. Open, Rusedski's temper caused him to squander a lead against Todd Martin and lose the fourth round match; notable about that match was Rusedski losing 14-plus consecutive points during the fifth set. Rusedski had made derogatory comments about Henman after a loss to his fellow Briton during the 2002 season. In the 2002 U.S. Open of that year, after being dispatched by Pete Sampras in the fourth round after a gruelling 5-set match, Rusedski made unsportsmanlike comments, calling Sampras "a half-step slow", and predicted that Sampras would lose his quarterfinal to young German star Tommy Haas. Sampras however went on to win the tournament. In the 2003 Wimbledon tournament, Rusedski swore at the umpire in the second round after not being allowed to replay a point after fan interference, losing his temper and ultimately losing the match to Andy Roddick, 7–6, 7–6, 7–5.
Greg Rusedski was plagued by injuries in the last few seasons of his career. He also tested positive for nandrolone in January 2004, but was cleared of the charges in a hearing on March 10, 2004.
