James Riley Blake (born December 28, 1979) is an retired American professional tennis player. Blake is known for his speed and powerful, flat forehand. During his career, Blake had amassed 24 singles finals appearances (10–14 record), while his career-high singles ranking was World No. 4. His career highlights included reaching the final of the 2006 Tennis Masters Cup, the semifinals of the Beijing Olympics and the quarterfinals of the Australian Open (2008) and US Open (2005, 2006), as well as being the former American No. 1. His two titles for the United States at the Hopman Cup are an event record. Blake was a key performer for the United States 2007 Davis Cup championship team, going 2–0 in the championship tie vs. Russia at second singles.
Blake was born in Yonkers, New York, to an African American father Thomas Reynolds Blake and a British mother Betty. He has a brother Thomas, who has also been a professional tennis player, and three older half-brothers: Jason, Christopher and Howard, and a half-sister Michelle.
Blake started playing tennis at age five alongside his brother Thomas. When he was 13, he was diagnosed with severe scoliosis and for five years as a teenager he was forced to wear a full-length back brace for 18 hours a day, though not while playing tennis.
Blake attended Fairfield High School, where a schoolmate and childhood friend was future musician John Mayer. Blake was inspired to pursue tennis after hearing his role model Arthur Ashe speak to the Harlem Junior Tennis Program. He left Harvard University, where he was a member of the A.D. Club, after his sophomore year to pursue a career in professional tennis.
In 2005, Blake was presented with the Comeback Player of the Year award for his remarkable return to the tour. Later, in 2008, Blake was awarded another honor by the ATP, where he was named the Arthur Ashe Humanitarian of the Year. On July 3, 2007, Blake’s autobiography Breaking Back: How I Lost Everything and Won Back My Life, which discussed his comeback after his unlucky 2004 season, was released and debuted at No. 22 on the New York Times Best Seller list.
