Kang already had nine birdies against one bogey when he hit 7-wood from a fairway bunker to 18 feet on the par-5 closing hole at TPC Summerlin and made the eagle putt.
“Last few weeks I wasn’t driving it very good, but my iron play was pretty sharp and my putting was pretty good,” Kang said. “So I was just thinking if I can get my driver somewhere in play I could actually score better.”
Sungae Im made five straight birdies on the back and, along with an 8-foot eagle putt on No. 9 at the turn, shot a 63. He was joined by Charley Hoffman and Chad Ramey, who birdied all but two holes on the back nine.
Matthew Wolff, who lost in a three-many playoff last year at the TPC Summerlin, was among those at 64.

He hit a slight draw with his 7-wood out of the sand, and then Matt Kuchar was on the same line with a chip, allowing Kang to see the would would snap off to the left. He knew the eagle putt was good before it reached the hole.
“When the putt is 6 feet short of the hole it was just outside the right edge and I knew it was going to go,” he said.
The low scoring was not a surprise — it took 7 under to make the cut last year — especially in such calm, warm conditions.
