Australia's two young superstars of women's golf are in contention at the season's second LPGA major, the KPMG Women's PGA Championship at Sahalee Country Club near Seattle.
Melburnian Su Oh is on the leaderboard, tied-sixth after a second-round 69, while her former amateur teammate Minjee Lee of Perth is just outside the top 10.
Oh's two-under round at the tough Sahalee layout could have been better; she lipped out with a shortish birdie putt at the ninth hole, her last for the day. But it was one of the rounds of the day and at even par, she will be in the final groups tomorrow.
The 20-year-old Metropolitan Golf Club member is only two shots from the lead held by Mirim Lee of South Korea and Canada's Brooke Henderson at two-under overall through two rounds.
She is in position to overtake veteran Karrie Webb in the world rankings and replace her in the Australian Olympic team for Rio de Janeiro with a strong finish this week, currently ranked No. 62 after a breakout season. She needs to pick up 11 spots to overtake Webb, who is ranked 51st.
Ironically Webb has mentored both Oh and Lee, who were part of Golf Australia's Karrie Webb scholarship squad for young amateurs at the time they were members of the national team that won the world amateur teams event in 2014. Lee, at world No. 13, is comfortably in the team for Rio.
Webb is tied-46th at Sahalee at six-over par.
World No. 1 Lydia Ko of New Zealand is also in the running at one-under in grinding conditions and heavy rain today, with just five players under par through 36 holes.
