The 15-year-old will become the first diver to compete for Wales in 20 years.
Heslop, who won a medal at last year’s European Junior Championship and FINA Grand Prix in Madrid, booked his place at the Gold Coast with a sensational performance at Scottish National and Open Championships at the start of December.
The city youngster won the men’s platform event in Edinburgh and in the preliminaries scored a massive 465.35 points, which was well over the consideration score for the Commonwealth Games.
Heslop, who will be in action this weekend at the British Diving Championships at the Life Centre, was one of 93 athletes confirmed in the Wales squad on Wednesday morning. Also in their team was former Plymouth College swimmer Calum Jarvis and sprint hurdler David Omoregie, who will be one of the main rivals to Plymouth’s David King.
Helen Phillips, chair of the Commonwealth Games Wales Board who confirmed the selections, said: “We are very excited about today’s announcement. This marks a major step towards completing the full Team Wales squad for the Gold Coast Commonwealth Games.
“Being selected for Team Wales is a huge honour for these elite athletes, and is a result of all the hard work and dedication that they have already put into training and competing at the highest level of their sport.
“We thank all the coaches and support staff, national governing bodies, Sport Wales – as well as the athletes’ friends and family – who have been instrumental in helping them along the way, and who’ll continue to give their support throughout their journey to, and during the 2018 Commonwealth Games.
“The Team includes some well-established Welsh sporting champions, as well as highly promising budding talent which reflects the success and progress of sport here in Wales. The standard of athletes across the sports bodes well for a successful games and a continuation of Wales’s presence on the podium for many years to come.”
