Oh, with her father SG on the bag, played what she described as the more difficult front nine in 4 under par and then added birdies at the par five 12th and 15th hole before hitting a three wood to 15 feet at the last. When that went in she jumped to 10 under for the tournament and at that point had a two shot lead but within the hour she had been joined in the lead by Ariya Jutanugarn of Thailand.
Oh also played this event as a 15 year old last year, making the cut but finishing midfield. She was a quarter finalist at last year's US Amateur Championship, is a former Australian Junior Champion and finished runner-up at the World Junior Championship at Torrey Pines in the US so she is a talented youg lady heading for a significant place in the game.
She is excited about the potential of playing on Sunday with Karrie Webb should the seven time winner make a move later in the day but she has already a round of golf booked in with Webb on the Tuesday of the Australian Women's Open in Canberra in two week's time.
"Yes, she is really a legend (laughs). I just heard I am having a practice round with her in Canberra. So I'm pretty excited about that. Karrie would be awesome to play with. A lot of the girls from the Australian National Squad have met her, but I haven't met her yet. This would be a really good chance for me to meet her."
17 year old Jutanugarn recently led the qualifiers at the Ladies European Tour qualifying school after a stellar amateur career which included victories at the AJGA Thunderbird, Women's Western Amateur and the Canadian Women's Amateur. She therefore leads the first ladies European Tour event she will play as a cardholder. Ariya's elder sister led the qualifiers at the LPGA Tour Q School so this is quite a family.
When morning play finished Oh and Jutanugarn led by two over Korean LPGA Tour player Chella Choi and by three over first round leader Alison Walshe who could only add a round of 71 this morning to her opening round of 66.
