Bob MacIntyre credits caddie dad Dougie for second-round lead

“We were walking up the last and he said, ‘I think I might need to start negotiating a wage this week’,” MacIntyre said. “It’s an experience for both of us. He’s done a good job so far.”

The Scot also reflected on the events of last week, when news emerged that PGA Tour player Grayson Murray had taken his own life hours after walking off the course.

“It’s taken my mind completely off the game of golf,” MacIntyre said. “After the news of last week, things are a lot bigger than the game of golf.

“We are human beings and I’ve put my dad on the bag and we are just trying to enjoy it as much as we can because we don’t know how much longer we have got of that.

“There has been zero expectation as there’s been a lot going on this week. I came out here, put my dad on the bag and tried to play smart golf. I’m just trying to get into position for the weekend.”

MacIntyre is one ahead of Ryan Fox, with the New Zealander still to finish his final round, while American Joel Dahmen is another stroke further back.

Rory McIlroy tumbled down the leaderboard following his opening 66 with a 72 to sit two under at the halfway stage.
