Golf: Aussie storms five clear in Open's second round

Australian Andrew Martin has shown the field a clean pair of heels on day two of the New Zealand PGA Pro-Am Championship in Arrowtown.

Martin fired a blistering second round eight under par 64 to storm five shots clear of his nearest rival at 13 under the card. He birdied five of his first six holes and finished off with another birdie at the par five ninth.

The 27-year-old's round is all the more remarkable given he is struggling with a foot injury. Martin has plantar fasciitis and a blister on the same foot is not helping. But he says it didn't bother him too much. "The medical team's done a good job - they strapped it up and I only really noticed it for the last five holes."

Martin won the Australian Amateur Championships in 2004 but hasn't won a tournament since turning pro in 2006. But he has had several top five finishes on the PGA Tour of Australasia, including a second in February at the Queensland PGA Championship in Toowoomba.

He says that has given him plenty of confidence for this event.

Martin is looking forward to the new celebrity pro-am format for the final two rounds at The Hills.

He has a history of doing well in pro-ams but admits he has put too much pressure on himself in professional tournaments. He says playing alongside an amateur over the weekend will be a welcome distraction.

"Bringing a bit of the pro-am stuff in is a bit more relaxed. It's also good having my girlfriend Rachel on the bag - it's only her first couple of times caddying so I'm worrying about her going in the right spots".

A win in Arrowtown will set Martin up for the year. He has his eye on US PGA Tour School in September but is also conscious of earning enough money to retain his card on the PGA Tour of Australasia. "If I can have enough money up or a win before September, that just frees me up so I can focus on Tour School".

Martin wasn't the only player tearing up the course yesterday. South Korean Jin Jeong stormed into the top 10 at six under par with a sensational 10-under-par 62. He now shares the course record with Australian Peter Fowler, who set it at the 2007 Open.

Australian Andrew Kelly had the two best shots of the day, holing out with an eight iron from the fairway for an eagle at the par four sixth hole - then an ace at the par three 10th.

Sadly for the 24-year-old, the hole-in-one prize of a BMW 3 Series Sedan 335i only applies at the weekend.

The 62 professionals who have made the cut will be paired up with an amateur for the third round today.
