But just as a reminder of some of his achievements on the court, here are 10 things to know about the American’s incredible tennis career.
1. He's a Grand Slam champion. Roddick went on a 19-match winning streak in the summer of 2003, capturing back-to-back Masters 1000 titles in Montreal and Cincinnati prior to going all the way at the US Open. At Flushing Meadows, he rallied from two sets down and saved a match point to outlast David Nalbandian in the semifinals before beating Juan Carlos Ferrero in the final, 6-3, 7-6 (2), 6-3.
2. He’s a former No. 1. He reached No. 1 on November 3, 2003, two months after winning in New York, and spent 13 straight weeks at the top spot until Roger Federer took over on February 2, 2004. He’s the last man other than the Swiss, Rafael Nadal, Novak Djokovic and Andy Murray to summit the top.
3. He was year-end No. 1 in 2003. The Omaha, Nebraska native, who was 21 at the time, is still the second-youngest year-end No. 1 in ATP history. Lleyton Hewitt was 20 when he finished at the top in 2001.
4. He reached another four Grand Slam finals. Roddick made another US Open final in 2006 and three Wimbledon finals in 2004, 2005 and 2009, finishing runner-up to Federer in all four. He was a fixture at the business end of majors—contesting five more semifinals and nine more quarterfinals.
5. He won five Masters 1000 titles. In addition to his aforementioned triumphs in Canada and Cincinnati in 2003, the American also won Miami in 2004 and 2010, and another Cincinnati title in 2006. He is the last player before Federer, Nadal, Djokovic and Murray to capture five Masters 1000 crowns.

6. He won at least one ATP title in 12 successive seasons. He won 32 ATP titles in his career between 2001 and 2012. He actually won his last two shortly before he retired in 2012—Eastbourne in June and Atlanta in July, before retiring after the US Open in early September.
Fun Fact: Roddick’s first and last ATP titles both came in Atlanta, on clay in 2001 and on hard in 2012.
7. He’s the last American man to win a major AND to reach No. 1. Since he won the 2003 US Open, there have been 65 majors—Europeans have won 63 of them and a pair of Argentines have taken the other two.
8. He won almost three quarters of the tour-level matches he played. Roddick finished his career with a 612-213 win-loss record (.742). He was 426-138 on hard (.755), 86-22 on grass (.796) and 75-43 on clay (.636). He had an excellent 131-45 career record at the Grand Slams, too (.744).
9. He’s a Hall-of-Famer. He was inducted into the International Tennis Hall of Fame as part of the Class of 2017, which also included fellow Grand Slam champion and former No. 1 Kim Clijsters.
10. He knows Federer, Nadal and Djokovic’s games very, very well. You won’t find many people with more experience playing the Big Three—he faced them a total of 43 times, defeating the Swiss three times (3-21 overall), the Spaniard three times (3-7 overall) and the Serb five times (5-4 overall).
