Woods has two US Open titles to his name

Woods has not played competitively since the death of his father Earl on 3 May, although he has already practised over a "brutal" Winged Foot course.

The world number one said: "Without a doubt, I'll be thinking about my dad a lot the next two weeks.

"I've never had to experience anything in life like this and never had a nine-week lay-off before."

Woods has spent time in New Zealand since he last played, attending the wedding of his caddie Steve Williams.

Writing on his website, he said: "As for my golf game, I don't really know what to expect next week at the US Open.

It's not the putter's fault; it's the dude putting it Tiger Woods

"Hopefully, my game will be sharp. No matter what happens, it won't be from lack of effort on my part.

"I started grinding a few weeks ago and recently played a practice round at Winged Foot.

"I love the place, but it's the hardest member's course I've ever seen.

"The greens are brutal. They have a lot of undulation and you have to try and keep the ball below the hole.

"And it's long. You can hit driver on just about every hole you want. It will be quite a test."

Woods' last competitive round was at the US Masters in April, where he was criticised for saying he putted like a "spaz".

The 30-year-old later apologised for his remarks and revealed: "It was just one of those weeks where I couldn't make anything and it cost me.
