Back in 2013 at Merion, Mahan went into the final round just one stroke off the first place and shared the lead with four holes remaining.
He ultimately slipped back to fourth as he carded a five-over-par 75 in difficult scoring conditions, but took heart from the fact he had remained in contention to the end.
While some might look back at missing out on the title with disappointment, the 33-year-old wants to use what happened as a platform to success near Seattle on Sunday.
Mahan ??? with eight top-10 major finishes after he came ninth at the US Masters in April – said: ?????The mental grind of playing a major championship, especially a US Open, is really the test.
???The margin for error at a US Open is so thin. One bad shot can lead to a double-bogey quite quickly.
???A misstep here, a misstep there and all of a sudden you are three or four over. The pressure on each shot is really the challenging part.
???You have to do your best to remain free and confident in your abilities and just pick your targets and make swings.
???You can’t try to control a US Open by force or control your ball too much. You just have to be able to pick the lines you want to take, pick the targets you want to take and be aggressive.
???You are going to miss a putt. It’s all about how stable you are mentally, how focused you are in the present in what you have to do.
???Obviously you have to play great but how you handle adversity, your ability to key in for four days, is paramount.
???In 72 holes, a lot’s going to happen and the more you stay positive, stay in the moment, that’s going to lead to success.???
