Matthew Jones was the only Australian to survive the cut at the Sony Open with eight of his compatriots packing their bags after two rounds of action in Hawaii. KJ Choi (65) is the man to catch, his 11-under-par 129 the benchmark and put the Korean two shots clear of Kevin Na. Jones, 27, outshone his more fancied countrymen with a one-under-par 69 taking him to three-under and tied for 32nd with 36 holes to play He salvaged something for the large Australian contingent at the tournament, booking his place for the weekend with a round that mixed four birdies with three bogeys. Aaron Baddeley (72), Robert Allenby (71) and Peter Lonard (70) will all be watching the last two days of action after falling short of the cut. Others reduced to spectators for the rest of the tournament are John Senden (69), Nathan Green (73), Jason Day (70), Nick Flanagan (72) and David Lutterus. While the day was a tricky one for the Australians, Choi tamed the Honolulu layout for the second straight round. He sank six birdies against just a single bogey on the par-four second hole to remain atop the leaderboard. Starting on the back nine, Choi entered the turn at two-under. He bogeyed number two but birdied four of his last five holes, including three straight to close out the round and post an 11-under-par 129 after two days. Na was one shot better on the day, carding a six-under-par 64. Steve Marino shot a three-under-par 67, recording five birdies and a pair of bogeys to stand three shots off the pace. Fred Funk and Jimmy Walker are tied for fourth at seven-under-par. Funk carded a 64 on Friday, while Walker shot a two-under-par 68.
