Henrik Stenson has said that he produced some of his best golf of the season as he hit an opening-round score of 65 at the US Open.

The Swedish player is currently joint-top with Dustin Johnson on five-under-par, largely thanks to a fine finish which saw him shoot four birdies in the final five holes.

He told Sky Sports News: "Mentally I was in a good place. Ball-striking wise, I hit some real quality shots out there. I played as solid as I have all year. I set up a lot of birdie chances coming in and just rolled a couple of beauties in from 14 and on.

"This is one day out of four and we've got to keep at it if we want to be there on Sunday. Regardless of whether you like all the holes, you like some of the stuff on this course, I'm here to do a good tournament and a good championship.

"So just keep your head down and keep on going, that's what's going to get me in a good spot."

Stenson is yet to win a Major championship.
