World No.1 amateur Lydia Ko has a chance of winning for a second time on the LPGA Tour.
The 16-year-old Aucklander has carded a superb four-under-par 67 at the Hyland Meadows Golf Club in round two of the Marathon Classic to climb to tied fifth.
Ko, who is the youngest winner in LPGA Tour history, will begin round three only two shots back from the trio of leaders Spain's Beatriz Recari and Americans Alison Walshe and Paula Creamer who are on an eight-under-par total.
The New Zealand rep has kept alive her streak of never missing a cut in 22 professional tournaments - a record that goes back to her debut in the New Zealand Women's Open in 2010.
While Ko was solid in her opening round she was spectacular in round two.
She made the turn in two-under-par 32 and then added three more birdies coming home to get to a seven-under-par total and within one stroke of the lead. Ko's only bogey for the round came at the last.
The World No. 18 has enjoyed a phenomenal season in 2013. She has finished in the top-five on five occasions and in the top-10 on six occasions as she backs up her incredible season in 2012.
The New Zealand Women's Open champion is now in contention to win her second LPGA Tour title after coming close to winning a month ago in Arkansas.
She delivered a stirring challenge for the title in the final round only to come up two strokes short of the 12-under-par playoff total and finished tied fourth.
