With four top tens already, the twenty two year old has already indicated just what a force he might well become in the game but with a narrow but impressive one shot lead heading into the weekend at the TPC Deere Run he looks a genuine chance to break through for that maiden victory at this level.
Thomas' form in his last few events had been less than that he had produced earlier in the season although he indicated this week that recent results were a little misleading.
"I've really been playing well, I really have," said Thomas. "Even at the Travelers, even though I missed the cut, I played well. Just didn't get anything to go my way. I hit a lot of good putts that just didn't fall.
Obviously last week I played 69 great holes, and I had every bit of reason as anybody else to win that tournament, I just played a couple bad holes, and if it wasn't for that I'm right there. There's definitely more positives than negatives to take out of the last couple weeks. I've felt like I've been close, and it's getting closer to all putting together.
Thomas leads by one over Johnson Wagner and Tom Gillis with Scott Pickney, Daniel Summerhays and Will Wilcox another shot back in a share of 4th.
Of the more fancied candidates, pre-tournament favourite, Jordan Spieth, worked his way back to the edge of contention with a second round of 64 to move within five of the lead while course specialists, Steve Stricker and Zach Johnson are at 8 under par and four from the lead.
The leading Australian is Cameron Percy in 22nd position while Rod Pampling and Greg Chalmers also made the cut in 55th place.
