Short Putts: The lighter side of the game
The golf is serious stuff, but away from the course six of the American players are having a fun time hanging out together.
Rickie Fowler, Jordan Spieth, Jason Dufner, Justin Thomas, Zach Johnson and Jimmy Walker are all staying in a house a mile from Troon.
"We're having a great time at the house. We've got six of us staying over plus our chef for the week," said Fowler.
"It's fun. A guys week. We're having fun, playing catch and baseball in the backyard and stuff."
He admits to being impressed with Jason Dufner's baseball swing. "Duf's probably got the best swing of us all. He's a sneaky athlete," said Fowler.
King Louis of the 14th hole
A huge roar rang out across the course when former Open champion Louis Oosthuizen scored a hole-in-one on the 178-yard 14th.
It's Oosthuizen's second ace at a major this year after he hit a bizarre hole-in-one on the 16th hole at Augusta in the U.S. Masters.
Oosthuizen afterwards thanked his caddie Greg Hearmon for dissuading him from choosing a five-iron for the tee shot.
"Yeah, just a solid six-iron. I was thinking a little five, maybe, and my caddie convinced me it's just a normal six-iron, so I've got to give him a little credit for that," said Oosthuizen.
Monty dug deep for first shot
Colin Montgomerie was all smiles after launching the 145th Open Championship at his home course of Royal Troon.
'Monty' was afforded the honour of hitting the first shot of the championship and it was a challenge he relished, despite later admitting he needed to draw on some high-profile experiences to handle the nerves.
"It was a great honour for me and for the family and the members of Troon that I kicked this off this morning," he said.
"Of course there were nerves, but I sort of dug deep into the Ryder Cup ways, where I'd led off. It was that type of feeling."
Reed loving his Scottish stay
Truth be told there is not much to do in Troon apart from play golf, but American Patrick Reed likes it that way.
Reed, who lives in Spring, Texas which has a population of 55,000 (Troon's population is 15,000), was asked what he liked about Scotland.
"I would say the simplicity," he said. "When we were driving from the golf course to the hotel there's just a lot of farmland, a lot of sceneries.
"At home it's golf, then you sit in traffic...and then you get home and you're trying to go through a busy hotel so it's still stressful off the golf course.
"It's definitely a way different pace than back home."
