KIMBERLEY, South Africa (CMC) – All-rounder Nyeem Young struck a nerveless half-century to inspire a West Indies comeback as the Caribbean side overturned the odds to upset powerhouse Australia by three wickets, and register their first-ever win over the tournament favourites at an ICC Under-19 World Cup here yesterday.Chasing 180 for victory at Diamond Oval in the Group B opener, Windies Under-19s found themselves in danger of defeat when they crashed to 92 for five after 25 overs, leg-spinner Tanveer Sangha slicing through the middle order with four for 30.However, the right-handed Young arrived to stroke an audacious 61 from 69 balls, in an invaluable 78-run sixth-wicket stand with fellow Barbadian Matthew Forde (23), to rescue the run chase and lift Windies to a crucial victory.There was some late drama when both Young and Forde perished in the space of eight deliveries with 10 runs still required but Kirk McKenzie (seven not out) put any lingering doubts to rest with an imperious extra cover drive for six off the last ball of the 46th over, to end the contest in style.The new-ball fast-bowling pair of Jayden Seales (4-49) and Forde (3-24) had earlier conjured up incisive spells to send the Aussies tumbling for an inadequate 179 in the 36th over.Australia appeared set for a major total, at 158 for four in the 31st over, but Seales and Forde ripped through the middle and lower orders as the last six wickets fell cheaply for just 21 runs.Opener Jake Fraser-McGurk batted with composure to top score with 84 from 97 deliveries while wicketkeeper Patrick Rowe chipped in with 40 but Australia failed to find a lower-order effort to rescue their innings.The victory was a vital one for the Windies especially with another difficult encounter against England looming tomorrow at the same venue.Choosing to bowl first, Seales struck early when he had Liam Scott caught low down at cover for four with the score on 10 in the second over.Fraser-McGurk added 33 for the second wicket with captain Mackenzie Harvey (20) before two bizarre run-outs set in train a slide that saw the Aussies lose three wickets for 24 runs to be 67 for four in the 14th over.Jayden Seales celebrates one of his four wickets.
