India’s Anirban Lahiri shot five birdies and four bogies to finish with one-under-par 71 after the second round to tie at T15.
“It was a really tough day, I got off to an awful start. Quite honestly I felt like I played good. I hit a lot of fairways. It was tough with the wind. I thought the pins were really tucked away”, said Anirban.
List, who is looking to win on the PGA TOUR for the first time, carded five birdies, including one on the par-5 9th, his final hole, to move to 9 under.
“Some positive vibes there,” List said. “Anytime you get a bogey-free you are really happy about it. The wind was tricky but I was able to save par a lot and play solid in the back nine.”
Three-time TOUR winner Lucas Glover compensated for a pair of bogeys with seven birdies in a 67 and was tied for second with Scott Brown, who had a 70.
A day after firing a 63 for the first-round lead, Justin Thomas made a 74 to slip into a share of fourth with Australian golfer Cameron Smith (68) at 7 under.
Thomas took a three-shot lead into the second round, but an opening 3-over-par 39 on the front brought him back to the pack.
The second-round 74 is Thomas’ worst score since an 80 in the second round of The Open Championship
Jason Day also struggled en route to a 74 to fall back to 24th at 2 under.
Whee Kim (70) was the highest placed of the 16 South Korean players in the field at 6 under overall, tied for sixth with Patrick Reed (72), Chez Reavie (72) and another Australian, Marc Leishman (72).
Seung Yul Noh carded five birdies and closed with an eagle in a bogey-free 65 for the best score of the day, lifting him to even par overall.
Conditions so far have been windy and List said he expects that to be a factor on the weekend.
“If the wind does not blow out here, there will be a lot of birdies,” List said. “If the wind does blow, you can kind of be a little bit more strategic and try to make some pars out there.”
