An eagle late in his round catapulted the 2015 Australian Open Champion up the leaderboard, the day reversing an ordinary run of form in his opening three events of the new PGA Tour season.
Cameron Davis, who won the individual title at the World Amateur Teams Championship over this layout in 2016, made a solid start to the week in what were the more demanding afternoon conditions on the seaside layout, his round of 3 under 68 having him in a share of 42nd place after round one.
Davis made a strong move on his closing nine with four birdies before a frustrating bogey at the 17th hole but he gets the opportunity for better conditions with a morning tee time on day two.
Davis will be winging his way back to Sydney once his week has finished in Mexico as he looks to defend his 2017 Australian Open title.
Curtis Luck struggled to an opening round of 74 to be in a share of 123rd position.
New Zealander Danny Lee who appears to be buoyed by the arrival of his first born is also at 6 under and tied for 4th with Jones. Lee has been playing well in recent starts.
The leaders after day one are Matt Kuchar, Kramer Hickock and Domini Bozzelli who recorded rounds of 7 under par 64.
Kuchar is another to be jetting to Sydney next week for the Australian Open followed by an appearance at the World Cup the following week in Melbourne.
