Thomas Aiken of South Africa snatched the lead in the $2.3 million Avantha Masters after Saturday's dramatic third round in which he hit eight birdies and an eagle. Aiken, who began the day four shots behind the leaders, carded a flawless 62 to end the day at 18-under par 198, three strokes ahead of nearest challenger Liang Wenchong of China. One shot behind the Chinese were Kiradech Aphibarnrat of Thailand and David Drysdale of Scotland at 202, setting up an intriguing finale on Sunday at the Greg Norman-designed par-72 Jaypee Greens outside New Delhi.
