The 24-year-old, who was talked of as the next big thing ever since his debut in the Davis Cup match against Japan last year, created history in January by becoming the first Indian to reach the final of the ATP Chennai Open.
The University of Virginia graduate beat the likes of former World No.1 Carlos Moya and Croat Ivo Karlovic en route to the final.
Somdev spearheaded the Indian challenge in their Davis Cup second round win against Chinese Taipei and later along with Rohan Bopanna took India into the World Group finals after 11 years, beating South Africa at Johannsesburg in the play-off.
Somdev also became the first Indian men's player to qualify for the singles main draw of a Grand Slam event in seven years in the US Open.
2. Chinnaswamy Muniyappa (Golf):
For a man who caddied for one rupee during his childhood, winning the Indian Open in October was a life-transforming moment.
The win fetched Muniyappa the Rookie of the Year title after the 32-year-old finished his season in 10th place on the Order of Merit with $223,269 through one win and three other top-25 finishes.
The caddie-turned-pro was the lone Indian in Asian Tour's annual roll of honour.
