Min Woo Lee has joined compatriot and opening round leader Dave Micheluzzi to spearhead Australia's challenge at the Asia-Pacific Amateur golf championship in Singapore.
Lee, Australia's top-ranked amateur, endured a fluctuating round at the Sentosa Golf Club as the 20 year-old from Fremantle mixed six birdies with three bogeys and a double bogey before managing his second sub-par round of the tournament.
The world No.10 added a one-under 69 on Friday to his 66 to be among a five-way tie for seventh at five-under.
Micheluzzi blitzed the layout on Thursday with a course record six-under 64, but the Victorian came back to earth with a largely frustrating one-over 71.
"I didn't hit it close enough to get the chance at enough birdies, I was hitting it to like 40 feet on every hole," he said, explaining the seven-stroke turnaround.

"It makes it very tough to go low, you just can't miss fairways around here."
Micheluzzi and Lee were still within range of the tournament's ultimate prize - a start in next year's Masters at Augusta - by reaching the midway point three shots off the pace.
Highly-rated Filipino Lloyd Jefferson Go and Cheng Jin of China were atop the leaderboard after also firing back-to-back sub-par rounds.
After carding 65s first time out, the duo produced rounds of 67 to be one shot clear of South Korea's Jin-Bo Ha and Zheng Kai Bai (China) at eight-under.
India's Rayhan Thomas owned the round of the day after matching Micheluzzi's course record 64 thanks to seven birdies and just the one blemish.
Dylan Perry constructed the best Australian round with a 67 negating a 73 to leave him at even par.
Zach Murray was one-under thanks to a 69 while Blake Windred rounded out the Australian contingent at one-over.
Stifling conditions proved too much for Shae Wools-Cobb, who withdrew halfway through his round to be treated for heatstroke.
