John Senden has bounced back from two early bogeys to fire an impressive four-under-par 68 and rocket into second place late in the second round at the Masters.
Senden made bogeys on the opening hole and again on the fourth to fall back off the pace at Augusta National before going on his tear, carding six birdies in his final 14.
It catapulted the 42-year-old to second place, three shots behind 2012 champion Bubba Watson, who matched Senden's round of the day 68 to move to seven-under.
The Queenslander was flush with confidence from his recent win on the US PGA Tour and is now looking to become just the second Australian to win the green jacket.
''I was feeling pretty good out there,'' Senden said.
''I was reasonably relaxed and just playing shots and I was able to keep the momentum going my way and had the will to keep it going.''
Defending champion Adam Scott, the first Australian to win the Masters, started his second round poorly but showed some fight on the back nine.
Three bogeys in his opening five holes sent Scott back to even par for the tournament but with back-to-back birdies on the 12th and 13th and another birdie on the 15th he pulled back to even on the day.
He found himself in trouble on the last hole thanks to an errant drive into the pine straw but recovered nicely to close out a 72.
It left him at three-under par in a tie for third.
Earlier, Marc Leishman produced one of the all-time Masters meltdowns, birdying the opening three holes to take the outright lead before playing the final 15 in 10-over par for a 79.
The Victorian carded two doubles and six bogeys in a horror stretch of 12 holes and missed the cut by a shot.
It was better news for Steven Bowditch, a Masters rookie, who is hanging tough at two-over for the week after a 72, leaving him set for the weekend.
Oliver Goss, just 19-years-old, fired an impressive one-under 71 to be three-over for the tournament and the Australian will be crowned low amateur on Sunday after being the only one of six to make the cut.
He will celebrate his 20th birthday on Saturday with another round at Augusta National.
World No.4 Jason Day made the weekend on the number after a 73 left him at four-over.
