HONG KONG surged into contention for honours at the International Bowls Classic when they defeated Zimbabwe 24-21 in a tense quarter-final at the Kowloon Bowling Green Club yesterday. The territory's pair of David Tso and Bill McMahon, who qualified for the last eight by securing third place in Section One, staged a rousing comeback from 16-7 down to oust Zimbabwe's Mark McCormick and Phil Dale. In another stunning result, Scotland's Alex Marshall and Kenny Logan ended the superb run of Channel Islands' David le Marquand and Adrian Welch, who had previously won all 11 of their Section One matches. The Scots, who only narrowly qualified for the quarter-final after a 20-18 win over New Zealand in their final Section One pool match, were always in the driving seat and took the match 19-10 after 20 ends. Scotland will now face Welsh pair Robert Price and Philip Rowlands, who were taken to the wire by defending champions Craigengower Cricket Club (CCC), represented by Jacky Wong and Tony Chok, before winning 18-16. Hong Kong will meet South Africa's Neil Burkett and Donny Piketh, who were once again in good form to beat Kowloon Bowling Green Club's Noel Kennedy and Adam Poynton 26-14. But it appeared at one stage that Hong Kong would never get this far. After a close opening five ends, Zimbabwe stepped up a gear, leading 14-6 after nine and 16-7 after 11. The local pair, however, were determined to claw their way back into contention, and, on the 15th end, showed the first signs of a recovery. They picked up a five on the 15th to reduce the score to 15-18 and three ends later, scored four to level the score at 20-20. Zimbabwe skip McCormick edged his team ahead at 21-20, but Tso, who took the title last year with George Souza representing CCC, levelled it again at 21-21 in the penultimate end. Tso again produced the goods in the 21st end, giving Hong Kong a three-shot lead with his final bowl. McCormick, with his last delivery, failed to disturb Hong Kong's cluster of woods to concede defeat. But Tso and McMahon must lift themselves again for their semi-final against favourites South Africa. Burkett and Piketh will have extra incentive to defeat Hong Kong as the pair were beaten by Tso and Souza in last year's final.
