Bangkok: India's Shiv Kapur has zoomed to a one-stroke lead in the Volvo Masters Golf tournament in Bangkok. Leading overnight after a six-under 66 in the first round, the Delhi golfer fired a five-under 67 in the second. Overcoming a minor hiccup right at the end, he emerged as the sole leader at 11-under 133. He now leads fellow Indian Jyoti Randhawa by one stroke at the halfway stage. Randhawa shot the day's best round of eight-under 64 on the strength of a brilliant back nine.
