Teens stand in the way of sixth Open title for Karrie Webb

FORMER world No.1 Karrie Webb will have to overcome some of the best young players the women's game has produced if she is to win her sixth Australian Open at Royal Melbourne this week.

Webb, who in 2014 had her first million-dollar season for eight years, is scheduled to tee off in the marquee group at 7.50am today, alongside 2013 winner Jessica Korda and world No.4 Shanshan Feng.

That group will follow the trio that includes last week's Ladies Australian Masters winner, Su Oh (pictured).

The 18-year-old will tee up in her seventh Australian Open - a stretch that began when she won her way through qualifying as a 12-year-old in 2009.

Oh, who was born in Korea but came to Australia at the age of two.

She has played dozens of rounds at Royal Melbourne and expects it to be tough.

"You know the greens aren't too ridiculously firm or fast, which is great, I think," she said. "It's playable if you hit it right - you just have to miss in the right spots."

The winner of last year's world amateur championship - while completing her Year 12 studies - Oh is only one of a big group of superstar teenagers in the field.

Heading that list are 17-year-old New Zealander and world No.1 Lydia Ko and 18-year-old Brit Charley Hull, who last year became the youngest player to win the European Tour Order of Merit. Ko, Hull and South Korea's So Yeon Ryu will play in the afternoon marquee group.
