A panel of judges comprising representatives from GMR, SportBusiness Group and the Youth Sport Trust selected Silverton after he successfully completed a rigorous six-week application process.
Candidates were required to fulfil a range of tasks throughout the period, including a 24-hour fanzone challenge involving three finalists at last month's Rugby World Cup final.
The aspiring sports marketing professional is currently completing a week of media training with SportBusiness Group at the ATP and LTA World Tour Finals at London venue The O2.
Silverton will then head to Sydney to cover the Extreme Sailing Series in December, and is scheduled to report on sports and entertainment events including the Super Bowl 50 in California, 2016 UEFA European Championships in Paris, Sundance Film Festival and Olympic Games in Rio de Janeiro next year.
It is believed the apprenticeship, which was developed by GMR Marketing in collaboration with SportBusiness Group, will equip the 23-year old with 10 years of experiences in just 12 months.
Silverton said: "I’m ecstatic I have been selected, the feeling is incomparable to anything else. I don’t think it is going to sink in until I am on the plane to Sydney.
"This job is simply unbelievable, it combines quite literally every passion of mine with a mix of sport, travel, marketing, writing and presenting. I can’t tell you how many messages I’ve had from friends who are delighted for me but also a bit jealous."
Charlie Dundas, director of business development at GMR Marketing, added: "Each challenge we set brought out different strengths and weaknesses in the contestants.
"During the online vote, Ollie showed great creativity and character by producing extra tongue in cheek videos in different formats. In just over a week, two of the videos received 25,000 views with hundreds of shares."
