Hoshino and Lee set up Australian Open showdown

Japan's Rikuya Hoshino fired a flawless 65 Saturday for a share of the lead with Min Woo Lee at the Australian Open, while South Africa's Ashleigh Buhai moved into prime position to defend her women's title.

Six-time Japan Tour winner Hoshino hit four birdies and an eagle to reel in Australian overnight leader Lee in his bid for a maiden DP World Tour win.

Lee began the day in Sydney with a three-stroke lead from Scotland's Connor Syme and American Patrick Rodgers, but struggled with his putter to card a one-under-par 70, holing a pressure birdie at the last. 

It set up a re-run of last week's Australian PGA Championship in Brisbane, when Lee took a three-shot lead over playing partner Hoshino into the final day and hung on to win his third DP World Tour title.

"It's one of those days and hopefully I can get it going tomorrow," said Lee. "Today was a bit of a grind, I didn't feel like I had it all there, but still did some good stuff."

Lee opened with a birdie and it looked like he might run away with the lead.
