Padraig Harrington believes that he and his fellow golfers should not feel too affected by the wet weather ahead of this week's US Open.
The course at Merion has suffered heavy rain over the past few days, which has prevented players from getting in a full practice round.
"The key is not to get too bothered about [the weather]," Harrington told Sky Sports News. "The good thing with the US Open, to be honest, is that 18 holes of practice is plenty for a US Open style golf course.
"You've got to hit the fairways and hit the greens, it's not like you've got to spend a lot of time working out the golf course."
Tiger Woods, Rory McIlroy and Adam Scott have been placed in the same group for the opening round of the tournament on Thursday.
