A superb round of 62 gave South African Thomas Aiken a three-shot lead at the Avantha Masters on Saturday. China&aposs Wen-chong Liang is second while Thailand&aposs Kiradech Aphibarnrat and Scotsman David Drysdale are a further shot back in a tie for third in Delhi. But the day belonged to Aiken who hit a round of 10 under to take firm control of the Asian Tour event. “I concentrated very hard to play one shot at a time and it seemed to work. It just shows what can happen,” Aiken said after the day&aposs play. “I&aposve been playing very well the last four months and just haven&apost converted opportunities. Fortunately this week I&aposve converted a lot of the opportunities that I&aposve had. “The majority of them (putts) have gone in from inside 10 feet and that&aposs what makes the difference from a scoring point of view.” Liang hit a three-under 69 on Saturday and will need to improve if he wants to haul in the South African. Aphibarnrat was very impressive in shooting a 66 while Drysdale&aposs 68 keeps him in slight contention. Three players are tied for fifth, five shots off the lead, with Australian Scott Hend joined by Finland&aposs Joonas Granberg and England&aposs Tommy Fleetwood.
