World number one Lydia Ko shares the lead with Korea's Ha-Na Jang and Thailand's Ariya Jutanugarn after day two of the Australian Open - and with Charley Hull just two shots behind, let the weekend battle begin!

World number one Lydia Ko shares the lead with Korea's Ha-Na Jang and Thailand's Ariya Jutanugarn after day two of the ISPS Handa Women’s Australian Open - and with Charley Hull just two shots behind, let the weekend battle begin!

The top four have a combined age of just 76 and the oldest just 22 - it’s a new wave that appears set to rule Royal Melbourne. Jang's 69 was the only sub-70 round on a day when mother nature and the toughening Composite Course took a toll on the competitors.

With an average score of 76.4, rounds took almost six hours to complete after early-morning fog delays. So hard was the test that overnight leader Ilhee Lee fired an 82 in her second round to only scrape in one shot inside the five-over-par cut line.

Ko was spectacular in parts, firing an imperious eagle on the par-four 15th by holing out with a nine-iron from 124m. But the occasional bogey kept the chasing pack in the mix. Remarkably, only once – the 2012 Canadian Women’s Open – has Ko held or shared the lead after the first two rounds of an LPGA Tour event and gone on to win.

Jang, a multiple winner in Asia, is already making her mark in her maiden LPGA Tour season, riding a very simple game plan that gave up just two bogeys - and Jutanugarn three-putted the first hole, but ignited her round with a long eagle on the par-five 10th to shoot a 71 before promising tomorrow’s big occasion wouldn’t alter her game plan.

Of the Australians, Queenslander Katherine Kirk is best placed to strike, tied for eighth at one under despite missing several makeable chances with the blade late in her round. Perth’s Minjee Lee made a solid move, firing a two-under-par 71 to slide into the top 20 in just her third tournament as an LPGA professional.

But the biggest local news was that of Karrie Webb’s battle to make the cut. The world No.9 made a par up the last to stay for the weekend, although she’s 11 shots from the lead and with her title defence in doubt.

Comeback queen Rachel Hetherington also made the cut on the number with a par on the last to finish over. Remarkably, Webb and Hetherington will play together in the second group out on Saturday morning at 7.55am.

Among those who missed out were past winners Yani Tseng and Laura Davies while Aussies Sarah Jane Smith, Stacey Keating and last weekend's Ladies Masters winner Su Oh will all get a sleep-in.
