Somdev Devvarman ( Bengali: সম্দেভ দেভ্ভার্মান born in 13 February 1985), is a professional Indian tennis player. Three of Devvarman's college conquests, John Isner, Kevin Anderson, and Jesse Levine have successful pro careers. He hit the headlines for being the only collegiate player to have made three consecutive finals at the NCAA, winning back-to-back finals in his junior and senior years. Only three other players have matched that record since 1950. His 44–1 win-loss record in 2008 at NCAA Men's Tennis Championship is unprecedented.

His best achievement so far on the ATP World Tour has been reaching the finals of the Chennai Open in 2009, as a wild card entry. In 2010, Somdev won the Gold medal in the Men's Singles event of XIXth Commonwealth Games at the R.K. Khanna Tennis Stadium in New Delhi and followed it up with both Men's Singles and Doubles Gold in the 2010 Asian Games in Guangzhou, China. He is coached by Scott McCain.

In 2011, Devvarman received the Arjuna Award from the Indian government for his national tennis successes.

Tommy Haas (born 3 April 1978 as Thomas Mario Haas) is a German and recently naturalized American professional tennis player. He has competed on the ATP Tour since 1996. After breaking into the World Top 100 in 1997, and reaching a career-high singles ranking of World No. 2 on 13 May 2002, Haas's career has been interrupted by injuries: whilst a professional, he has twice dropped out of the world rankings due to being inactive for twelve months. His first period of injury saw him miss the whole of the 2003 season, and he did not return to the world's top ten until 2007. He also missed over a year's tennis between February 2010 and June 2011, but has since returned to play on the Tour.

Haas has never won a Grand Slam tournament, his best result being three-time semi-finalist at the Australian Open and one semi-final at Wimbledon. He has won thirteen career titles in singles and doubles, including one Masters tournament, and has a silver medal from the 2000 Summer Olympics.

His equipment include Solfire, Lacoste and Nike for his clothes and shoes, respectively. He switched to using Head racquets in 2009 after using Dunlop Sport racquets for most of his career.

Roddick has reached four other Grand Slam finals (Wimbledon in 2004, 2005 and 2009, and the US Open in 2006), losing to Roger Federer each time. He is married to Brooklyn Decker, a Sports Illustrated swimwear model and actress.

By winning three Majors in 2011, Djokovic became the sixth male player in the open era to win three Majors in a calendar year.

He is the first male player representing Serbia to win a Major singles title and the youngest player in the open era to have reached the semifinals of all four Grand Slam events, separately and consecutively. Amongst other titles, he won the Tennis Masters Cup in 2008 and was on the team which won the 2010 Davis Cup. He also won the bronze medal in singles at the Beijing Olympics in 2008.

Unlike many top tennis players, who have brilliant juniors careers and hit the ATP Tour in their teens, Isner didn't decide that he wanted to play professional tennis until he was 21.

Isner played collegiate tennis at the University of Georgia from 2004 to 2007 and became the school's all-time leader in singles and doubles victories, earning All-American honors each of his four years and leading Georgia to the 2007 NCAA championship.
