George McNeill, who won this event in 2007 and finished second last year, just eagled the Kodak Challenge hole (the par-5 16th) to get to 6 under on the day after seven holes. The eagle pushes him to 12 under for the week and into a tie for the lead with Ryugi Imada.
McNeill has a hard time explaining why he's so tough at TPC Summerlin. In nine career rounds here, he's broken 70 every time.
"I have no idea. I think I say the same thing every year because I get the same question every year," McNeill said. "I don't know why. Must have been just from the first year when I played here and I won, obviously I've had success here. I feel comfortable going around this golf course.
"I know where to hit it and where not to hit it. Whether the other guys have figured it out or not, I don't know. But it seems to me that I've somewhat figured that out."
