ONEIDA, Wis. (AP) Katherine Kirk shot a 7-under 65 on Saturday to open a four-stroke lead in the Thornberry Creek LPGA Classic, and move into position to challenge the tour's 72-hole record.
Coming off a career-best 63 on Friday, the 35-year-old Australian reached 20-under 196 in the first year event at Thornberry Creek - the Oneida Nation-owned resort near Green Bay.
The LPGA Tour record for 72 holes is 27 under, set by Annika Sorenstam in the 2001 Standard Register Ping in Phoenix and matched by Sei Young Kim last year in the Founders Cup, also in Phoenix. Sorenstam shot a record 59 in the second round.
Kirk played the first five holes in 1 over with a birdie on No. 1 and bogeys on Nos. 3 and 5. She rebounded with a birdied on No. 6, ran off four straight on Nos. 8-11 and added birdies on 13, 15 and 17. On the par-4 18th, she saved par with a 15-footer after finding the right fairway bunker and hitting her approach well left. Kirk won the last of her two tour titles in 2010.
South Africa's Ashleigh Buhai was second after a 65.
