Thompson parachuted, with a Navy SEAL at her back, from 10,000 feet onto the first tee of the LPGA Tour's Kingsmill Championship pro-am.
Thru the first two rounds at the LPGA Kingsmill Championship, no one could seem to catch American, Lexi Thompson.
Thompson had three birdies Saturday and made bogey on the par-3 17th for the second time this week.
Kang, who has not won in her six seasons on the LPGA Tour, came closest on Kingsmill's River Course as a rookie in 2012, when she finished tied for third.
Ko's position as world number one has been under pressure recently from two challengers, Korean So Yeon Ryu and Thailand's Ariya Jutanugarn.
Gerina Piller watches her tee shot on the ninth hole during the second round of the Kingsmill Championship LPGA golf tournament in Williamsburg, Va., Friday, May 19, 2017.
"I couldn't sleep because of my putting", Kang said. She reached the par-5 15th with driver and 6-iron.
Thompson dropped a shot late in her round but she is in such dominating form this week, having led from wire to wire, that those chasing her tomorrow will need a very low final round and a little help from Thompson herself. Sunday is an important round for the rookie who looked ready to set the world on fire previous year when she was dominating the Symetra Tour.
"It was really tough out there with the wind action being opposite to what we've played the last couple days", Ko said.
Another solid day for Chun, who carded a 4-under, 67, to sit three shots off the lead, but she said she feels her swing has been off this week. "When you do get the birdie opportunities, try and hole it".
"I'm used to Bernhard being on the top", Funk said.
Piller shot a 67, closing birdie-bogey-birdie-bogey.
Ko, trying to fight off rivals and remain atop the rankings, fired a bogey-free 67, opening with a birdie on the par-4 10th, adding back-to-back birdies at the par-5 third and par-4 fourth and another at the par-5 seventh.
She had started with a birdie on the par-five third, but bogeyed holes eight, 10 and 12 as it looked like she would fall out of contention.
Ko birdied her first hole of the day, before reeling off nine consecutive pars to stay steady through the middle of her round.
