Jessica Korda shot a course-record 62 at the LPGA Thailand on Friday to lead by four strokes after the second round.
"I didn't know it was happening", said Korda who has a new caddie on the bag this week in veteran Colin Cann.
"I just hit the collar. It was a pretty cool round".
Korda dropped in four consecutive birdies starting at the 13th and closed with a 29 on the back nine.
Korda is making her season debut in Thailand after the surgery and is playing with 27 screws holding her jaw in place.
She's trying to become the first Thai victor of the tournament.
"It was great out there, me Jess (Korda) and Brooke (Henderson) were doing well and feeding off each other", said Lincicome. I have a couple of screws in my face.
"I didn't feel happy like I did on the first day".More news: Vehicle strikes security barrier by White House, driver apprehended

"I had no pain, [I was] just numb. The headaches are gone".
Lincicome carded an eagle of her own and just missed another, turning in a brilliant round to back her opening 67 with a 65. I made an eagle today, which is really fun.
Lee, coming off a strong T5 finish at last week's ISPS Handa Women's Australian Open in Adelaide, will start round two tomorrow tied with American Lexi Thompson and hometown hero Moriya Jutanugarn after the pair fired opening six-under-par 66s in Chonburi.
During the second round of the Honda LPGA Thailand, Lexi Thompson incurred a two-stroke penalty on hole 15 for breach of the Local Rule regarding temporary immovable obstructions as prescribed in Appendix 1.
