Will Yanagisawa, who was medalist at Q-School last week, notched a 65 to move into a tie for fourth at minus-8. He was joined there by Brian Guetz.

The 38-year-old ran off three straight birdies from the 10th to move to the top of the leaderboard. Gomez birdied the par-3 14th, before parring his final four holes to share the lead.
'You have to have a lot of things go your way to win a golf tournament,' Gomez said. 'You have to take each day as it comes. My approach on Sunday will be the same as any other round. Get a feel for the round, see where it is going and we'll see where I am when it's all over.'

'This game hasn't been as fun as it should be for me lately,' said Taylor. 'There's no sense putting any pressure on myself. I'll go out there, hit it, find it and hit it again. I didn't make many mistakes.'
