Pettersen targets top spot

Suzann Pettersen has a chance of achieving her ambition to become world No 1 this weekend.

The 32-year-old Norwegian can replace Park In-Bee at the top of the rankings if she wins the HSBC Women's Champions in Singapore and the South Korean does not finish better than tied for third with two players.

"I think I can be good enough to be the best in the world, otherwise I don't think I would have kept playing. So that's my motivation every day," said Pettersen.

"I think the eternal drive of trying to get better every day is what gets you up in the morning, what gets you through the tough days, the good days.

"It's obviously a dream of mine to become the best female golfer in the world, I'm not going to hide that. But at the same time, I just want to see how good I can be."

Park, who finished second on her seasonal-debut in Thailand last week, is expecting a shift in the rankings this year with both world No 2 Pettersen and third-ranked American Stacy Lewis - the defending champion in Singapore - ready to mount a challenge.

The 25-year-old said: "It's actually really tough to win every tournament. It's only my second week back this year and I think rankings points-wise there's not much of a gap between one to three. So obviously there are going to be some changes this year."

Nineteen of the top 20 players in the world are set to play at the par-72 Sentosa Golf Club this week with coverage of the first round on Sky Sports 4HD from 10.30am on Thursday.
