Jones, who played well in this event twelve months ago when finishing 13th after being in 3rd place heading into the final round, again showed his liking for the wide-open expanses of the Ben Crenshaw / Bill Coote designed layout.
Five birdies and four bogeys led to a round of 70 leave Jones in a share of 10th place at the halfway mark, a bogey at his final hole perhaps a disappointing way to complete his round but he is still well enough placed on a golf course he clearly enjoys.
Cameron Davis is the next best of the Australians in the field, the Sydney golfer in a share of 17th place and just one shot behind Jones.
Davis has struggled since joining the PGA Tour via the Web.Com Tour Finals last year and has missed his last four cuts but this has been an encouraging week to date for the 24-year old, now Seattle based golfer.
Curtis Luck jumped 64 places with his second round of 67 today to be in 36th place, the West Australian the only other Australian to make the cut.
The 36 hole leader Sung Kang recorded six consecutive birdies in the middle of his round before signing for a record-equalling round of 61 to snatch of four-shot lead over Matt Every and Tyler Duncan with Brook Koepka another shot back in 4th position.
