Just months after winning gold at the Carifta Games in Bermuda, Trinidad’s Keshorn Walcott has become the youngest ever Olympic javelin champion.The 19-year-old claimed a surprise win on Saturday night, hurling the spear 84.58 metres to upset a strong field in the men’s event, including Norway’s two-time Olympic champion Andreas Thorkildsen.It was Trinidad’s first Olympic gold since Hasley Crawford won the 100 metres at the Montreal Games in 1976.Walcott’s unforeseen win might not have come as such a shock to those who saw him storm to victory with a throw of 77.59 metres at the National Sports Centre (NSC) in April.“I’m more than stunned,” Walcott told the Trinidad Express “I just went into the final to enjoy it, so to come out with the gold medal is a feeling I can’t describe right now.“I know everyone is proud of me,” he continued. “I’m just thankful for all the support. I’m going back to the Games Village to celebrate with the team, and we’re leaving (today), so we’ll celebrate in Trinidad too. I know they’re going mad in Toco.”Walcott is the latest Caribbean athlete to have gone on to bigger and better things after competing at a Carifta Games held in Bermuda.Jamaica’s sprint sensation Usain Bolt, who claimed three golds at these Games, became the first junior athlete to break 20 seconds in the 200 metres at the 2004 Games at the NSC.And while he may not have competed at Carifta in Bermuda, Kirani James of Grenada, who did attend this year’s Games to present medals, also helped ensure the Caribbean more than made a mark at London 2012, winning gold in the men’s 400 metres.Grenada’s prime minister declared a half-day holiday on Tuesday and gave the entire island the afternoon off to celebrate the 19-year-old’s medal.It was the first Olympic medal won by an athlete from the tiny south-east Caribbean island, which has a population of around 110,000.
