He successfully defended his title, winning gold again at the 2012 World Junior Championships in Athletics. Gill throws with his right hand, using the spin technique. == Career == Gill first came to prominence in late 2009 when he set world age-14 bests with the 5kg Shot (20.42m) and 6kg Shot (17.41m).〔(【引用サイトリンク】title=In Final Year As A Junior, Gill Already Has Sights On Senior Success )〕 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.〔(【引用サイトリンク】title=2010 World Junior Championships in Athletics: Men's shot put (final) )〕 In 2010, prior to 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).〔(IAAF Youth All-time Shot Put list )〕 On 26 March 2011, at the New Zealand National Championships, Gill achieved 21.34m with the 6 kg shot, at the time ranking him 4th on the all-time IAAF junior list for shot put.〔(IAAF Junior All-time Shot Put list )〕 On 23 April 2011, at 16 years of age, Gill threw 20.01m with the senior shot (7.26 kg). Gill's throw broke the 44-year-old New Zealand national record set by Les Mills in 1967. This performance surpassed the standard for the 2011 Athletics World Championships, however the rules for that competition exclude anyone of Jacko's age competing in any throwing events. An appeal to the IAAF for an exception to be made to this regulation to allow Gill to compete was rejected. The performance also surpassed the B standard for the 2012 Olympics〔(IAAF: QUALIFICATION SYSTEM – GAMES OF THE XXX OLYMPIAD )〕 however not only was it outside the qualifying period (which started on 1 May) it was also less than the qualification standard (20.30m) subsequently set by Athletics New Zealand.〔(2012 Olympic Games - London: Selection Criteria )〕 However, he did go on to qualify for the 2012 Olympics on 5 December 2011 by throwing 20.38m.

Gill has been reported as the youngest and one of the lightest athletes〔 to throw over 20m. On 7 July 2011 at the 2011 World Youth Championships in Athletics in Lille Métropole, France, Gill won the gold medal by 4m with a World Youth Best Performance of 24.35m,〔,(IAAF World Youth Championships: Boys Shot Put Final - Gill beyond 24m, three times! )〕 which he subsequently improved later that year with a throw of 24.45m in Auckland on 12 December. In 2013 Gill broke the Oceania Junior Record with 22.32m at Brisbane, Australia on 20 July〔(IAAF Outdoor Junior list 2013: Shot put )〕 and then with 22.54m at the North Shore, Auckland on 4 August.〔(Athletics New Zealand: Cross Country Champs, Jacko Extends 6kg Shot Record & Weekly Roundup )〕 On 18 August, also at the North Shore in Auckland, he threw 23.00 to break the World Junior Record.〔〔(Stuff.co.nz Gill breaks world junior shot put record )〕 On 25 June 2014 in Rarotonga, Gill improved his personal best to 20.70m in winning the shot put title at the 2014 Oceania Area Championships in Athletics. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Jacko Gill」の詳細全文を読む スポンサード リンク
