The defending champion and world golf number one Jordan Spieth has a simple game plan after surging into Australian Open contention with a solid if unspectacular second-round three-under-par 68.
"Right now I think the goal is going to be to try and shoot 10 under on the weekend and I think that should be good enough," Speith said matter-of-factly after drawing to within four of the lead.
Spieth is three under for the championship after squeezing everything out of his round.
"I certainly could have shot worse had my short game not been there, especially on that front nine," he said.
Australian Matt Jones is the player Spieth must catch.
Jones followed up his first-round 67 with a 68 to be on track to win his national championship for the first time.
Daniel Pearce is the best placed New Zealander in the field.
He's in a five way tie for ninth at one under, having shot a two under par 69 in the second round.
