ROGERS, Ark. – The battle to secure the No. 1 spot in the Rolex Rankings is expected to continue in September at the P&G NW Arkansas Championship presented by Walmart. Tournament officials have announced today LPGA Tour professional Cristie Kerr, who currently holds the No. 1 position, has committed to play in the event. Kerr will be joined by Ai Miyazato (No. 2) and Suzann Pettersen (No. 4), as well as defending champion Jiyai Shin (No. 3), who previously announced her return. The P&G NW Arkansas Championship presented by Walmart will be held, Sept. 6 – 12, 2010.

"Our expectation this year is that we will have the best field of players ever for our event," said Jay Allen, Tournament Chairman.  "We have a championship caliber golf course at Pinnacle and a purse of $2 million this year, and the top players in the world are clearly responding to this."

Kerr reclaimed the top-ranked position earlier this week. She originally held the position for three consecutive weeks in late June and early July due to her wins at the LPGA State Farm Classic and LPGA Championship presented by Wegmans, before losing it to Ai Miyazato, who now holds the No. 2 position. Kerr has carded six top-10 finishes for the year including another top performance as a runner-up at the 2010 HSBC Women’s Championship.

Miyazato, of Japan, began the 2010 LPGA Tour season strong, carding three wins in her first five events. Her fourth win at the Shoprite LPGA Classic propelled her to the No. 1 position, before losing it to Kerr. Miyazato has also carded six top-10 finishes for the year.

Norway’s Pettersen continues to search for her first LPGA victory of the season after carding six top-5 finishes on the year. Pettersen has runner-up finishes at the Honda PPT LPGA Thailand, the Kraft Nabisco Championship, the Bell Micro LPGA Classic and the U.S. Women’s Open. She has held the No. 4 position for four consecutive weeks.
