World number one Tiger Woods is focusing on taking the positives from his US Open performance despite posting his worst score ever at a major on Monday morning.

The 37-year-old's challenge was already effectively over before the final round and he ended 13 over after a 74 that included a triple-bogey on the second.

Despite his bad weekend, the American is adamant that there are a lot of good points to take from the tournament.

"It was a good week overall," Woods told Sky Sports News. "There's always a lesson to be learned in every tournament whether you win or lose. I'll look back at the things I did right and the things I did wrong.

"I did a lot of things right. Unfortunately I did a few things wrong, as well. I struggled with the speed all week. These greens are grainy. It's one of the older bent grasses creeping bent. I struggled with the speed, especially right around the hole. Putts were breaking a lot more. I gave it a little more break and then it would hang. That's kind of the way it was this week.

"I'm sorry that the golf wasn't what I would have liked but it was a fantastic atmosphere, the people were into it. Obviously there weren't as many people as some of the US Open sites, but this was I think more intimate. People were very close to you. Sometimes we get a lot of people, like at Bethpage, but they're so far away from us. Here, because the property is so small, I think the galleries were a little bit closer than they have been in most US Open sites."

Englishman Justin Rose held his nerve to win the title at Merion.
