Jacko Gill first came to prominence in late 2009 when he set world age-14 bests with the 5 kg Shot (20.42m) and 6 kg Shot (17.41m).At the 2010 World Junior Championships in Athletics, as a 15-year-old, Gill won the gold in the shot put (6 kg) with a distance of 20.76m, beating 18- and 19-year-olds and becoming the youngest-ever male junior champion. In 2010, after the World Junior Championships, Gill threw the 5 kg shot 22.53m at an event in Stockholm, Sweden, exceeding the best-known performances with that weight for 15- and 16-year-olds. He improved to 22.60m in finishing second at the inaugural Youth Olympic Games despite being unwell. On 11 December 2010, at the New Zealand National Secondary Schools Championships, Gill set a youth (under-18) world-best performance of 23.86m (5 kg) just 10 days before turning 16 . He improved this world youth record to 24,45m in 2011. At the time of these performance he had a body weight well under 100kg . Then it was ”discovered” that his technique was quite different from the standards set by the world best throwers , mostly American , until it was found that he had achieved a perfect combination of rotational spin with a linear delivery , taking advantage of both techniques and this could explain the incredible performances …added to the fact that his conditioning preparation was also out of the usual paths .
