Heavy winds cut short the first round of the Africa Open on Thursday, with Jaco Van Zyl on top of the leaderboard at six under. South African Van Zyl is looking to maintain an unbeaten run of locals winning the tournament hosted at East London Golf Course, and took the clubhouse lead with a first-round 66 that included an eagle on the par-five 15th. In pursuit is Brazil&aposs Adilson Da Silva, who began in blistering fashion to be five under through eight holes when darkness stopped play after heavy gusts had halted play earlier in the day. In outright third spot is England&aposs John Parry, with his four-under 68 seeing him mix three bogeys with seven birdies. South Africans Oliver Bekker and Andrew Curlewis head into Friday&aposs play on three under, with Bekker shooting a 69 while Curlewis is through eight. Finland&aposs Mikko Korhonen is also on three under, courtesy of a birdie and an eagle through 11 holes. There are 12 players tied for seventh spot – with Frenchman Gregory Bourdy and Tjaart Van der Waalt, a previous runner-up in Cape Town, among the five to have signed off on an opening-day 70. Swede Bjorn Akesson, England&aposs Andy Sullivan and South African Daniel Green are also in the clubhouse on two under. Still to finish their opening 18 holes are Norway&aposs Morten Orum Madsen (through 16), Spain&aposs Ignacio Garrido (15), Swede Michael Jonzon (14) and Chile&aposs Mark Tullo (12). Locals Justin Walters (14), Darren Fichardt (12) and Derik Ferreira (10) are also on two under overnight. Scott Arnold, five shots off the pace, is the best placed Australian.
