Cameron Norrie only turned professional four years ago, but can now call himself the British number one, a member of the world's top 16 and a Masters Series champion.
The 26-year-old has risen from 74 in the rankings at the start of the year by recording 47 wins, winning two titles, and reaching four other finals.
With a strong performance in Paris next month, in the final Masters event of 2021, Norrie could still qualify for the ATP Finals, involving the best eight players of the year.
His story started in Johannesburg, and has ended up in London via Auckland and Texas Christian University - where he laid the foundations for a rapid rise up the rankings.
