Spieth ready for US Open defence

Jordan Spieth has put his Masters collapse behind him and insists it will not interfere with his preparations for this week's US Open.

Spieth appeared to be on course for a second successive Green Jacket when he moved five clear of the field with just nine holes to play at Augusta National, but he dropped six shots in three holes, including a quadruple-bogey at the par-three 12th, and Danny Willett took full advantage to land his first major.

The 22-year-old bounced back to win the Dean & Deluca Invitational at Colonial Country Club in Texas at the end of May and the world number two will be drawing on that experience when he bids to defend his US Open title at Oakmont.

"I moved on. We went and won, and I think that was really big for us to actually win a tournament. Not just contend, but to actually close one out, and so now I can draw back on those last few holes, the pressure that I felt," Spieth told a news conference.

"So honestly I think it's out of our heads now just from that one experience at Colonial.

"I think, if you're coming off a recent win, getting back into contention is a more natural state. If you're coming off kind of a heartbreaking loss, getting back into contention can be fearful and you've just got to push through the fear. And I feel like we got through that."

He went on: "I feel very confident about my game right now. I wish the tournament started tomorrow.

"I haven't felt like a defending champion. There's been no festivities. It just honestly feels like a normal week that I got here earlier for, and I'm preparing maybe harder for.

"Coming in as the defending champ can certainly help me if I get into contention.

"But as far as getting moving this week and my preparation, it really feels like a normal event, which is nice."

Spieth could add an Olympic medal to his list of achievements later this year if he decides to play at the Rio Olympics.

Although he is wary of the threat of the Zika virus, the American is looking forward to the prospect of representing his country in Brazil.

"I'm not sure where I'll play next, even after this week," he stated. "But right now, I'm pretty confident with what we've heard from not only the PGA Tour but our personal outreach, and I think being an Olympian is just an absolute tremendous honour.

"Do I think being an Olympian outweighs any significant health threat? No. If I thought that the threat was significant, I certainly would not go.

"But based on what's come to my knowledge at this point, it seems like it's going to be an extremely memorable experience and I look forward to trying to win a gold for the United States."
