Teen prodigy Ko says no to turning pro - coach

New Zealand's teenage golfing sensation Lydia Ko will resist pressure to turn professional following an eye-catching performance at the Women's Australian Open, her coach said on Monday.

The 15-year-old, already the world's No 1 amateur and the youngest tournament winner in US LPGA history, came close to upsetting South Korea's Shin Ji-yai before a poor final round saw her relegated to third.

Her form at the Royal Canberra Golf Club, which included a career-best 10-under-par 63 in the opening round, has a number of pundits, including Tiger Woods's former caddy Steve Williams, calling for her to turn professional.
