Kerr extends lead to 11; Ai stumbles

PITTSFORD, N.Y. -- Cristie Kerr is walking down the fairway in a near-sprint, ready to get this round over and done with. She is playing safe but flawless golf and has recorded four birdies on the day while her nearest opponents seem to be backing up. At 17-under, her lead is now 11. If she gets to a 12-shot advantage by the end of the round, she breaks the record for largest victory margin in LPGA Championship history, which was set by Betsy King in 1992.

Meanwhile, Ai Miyazato bogeyed the 18th to fall back to five under, one behind Song-Hee Kim who's in second place with four holes to play. Unless Kim bogeys at least twice on her way home (and unless Jiyai Shin, who's tied with Miyazato at -5, bogeys at least once), Miyazato will lose her top spot in the Rolex World Ranking to Kerr. Still, Miyazato was in great spirits after her round. "I'm happy," she said. "I played really well today. I did my job." When asked what she thinks about Kerr's performance so far, she said, "Seventeen under is almost too good. My caddie and I thought five- to eight-under would win this week. She is just amazing."
