Luck’s 2 under 68 has him six shots from the lead of Scott Piercy who leads by two over Hideki Matsuyama and Adam Hadwin.
Luck, who was out in the afternoon field, began with a three-putt bogey but rallied back to reach 3 under through 10 holes before bogeys at the 15th and 16th holes.
Luck would then birdie the 17th after a great tee shot to 6 feet and the lengthy par 3 and added another at the last when holing from 12 feet at the par 5.
Luck has missed the cut in four of his last five starts on the PGA Tour and has yet to record a top ten since gaining his PGA Tour card via the Web.Com Tour Finals late last year.
The West Australian, former USA and Asia Pacific Amateur champion, is currently 160th in the Fedex Cup standings and with less than two months of the regular season remaining he needs to build on this start.
Jason Day recovered from a slow start to his round with a back nine of 32 for a round of 69 to be in 49th place and seven from the lead.
Cameron Davis and Rod Pampling had rounds of 70 while Matt Jones struggled to a round of 74.
Piercy leads at 9 under 62 continuing what has been a good season to date. He was runner-up in Dallas and 3rd at the Heritage Classic and with six birdies in his last eight holes today he powered home to overtake Matsuyama and Hadwin.
Matsuyama, who appears to be closing in on another PGA Tour victory following some solid form of late having not missed a cut in nearly one year on the PGA Tour, bogeyed his final hole but he is well placed to win again.
