(CNN) -- His father is a nuclear engineer and his uncle was a high-ranking politician in Montenegro, but Milos Raonic is forging an entirely different career path with his own kind of power. At an imposing 6ft 5in tall, he has burst onto the tennis scene this year with a fast-developing all-round game based upon his booming serve -- he has already registered the third-fastest delivery on record. The 20-year-old is the highest-ranked Canadian tennis player in the history of the ATP Tour listings, he has won his first top-level tournament, and reached the fourth round of only his second grand slam event in Australia in January.
