Welsh golfer Jamie Donaldson believes the player who holds his nerve best on the greens will win the 2015 US Open in Tacoma.
The Ryder Cup star will start his tournament at 16:39 BST on Thursday and is hopeful of being in contention when the final round begins on Sunday.
"The putting is massive this week, you're going to be hitting it nowhere near pins," Donaldson, 39, said.
"The guy who gets the perfect speed of the greens is going to be up there."
Donaldson will play alongside Americans Patrick Reed and Chris Kirk in his first round at the Chambers Bay course, starting on the 10th tee.
"Scoring is paramount obviously - the fairways are quite wide in places, so there's not much skill in certain areas, then on other holes it's quite tight," Donaldson said.
"I had a bit of an injury wobble last week, which didn't help, but I was OK playing a tournament.
"I came out last week to use it to get over jet-lag, done that so I've got no excuses.
"I've been hitting pretty good, so it's just a case of taking that into the tournament and cracking on."
Donaldson has been impressed with the course during practice in Washington State and believes it could suit players who compete more regularly on the European Tour.
"It is different, it's more of a European golf course - it's beautiful to the eye, it's great to look at," he added.
"It just depends on how it's set up: they could make it very tricky, which could be slightly farcical; or if they don't go crazy with it it could be a great week on a what is a really nice golf course."
