Crisite Kerr is the new top-ranked women's golfer after her impressive run away victory at the LPGA Championship.
Kerr carded a six-under final round 66 for a 19-under 269 total, leaving her 12 shots clear of the best in women's golf.
It was a record victory margin in the LPGA Championship, beating the 11-shot win for fellow American Betsy King in 1992.
Kerr was claiming her 14th career victory on the LPGA Tour and winning her second major after the 2007 U.S. Open.
Kerr is the first American to hold the number one rank since the Women's World Golf Rankings were introduced in 2006. She takes the top rank away from Japan's Ai Miyazato who was ranked first for the past week after Lorena Ochoa retired from the game and forfeited her rank. Miyazato is now ranked second after her fifth place finish this weekend.
Kerr is fully aware she will now come under pressure for the top ranking.
"I'm there now, but I have to prove that I deserve to be there," Kerr said. "So there is still a lot of work ahead. But it feels awfully good right now."
