Tiger Woods to play more golf to improve form

Woods is set to compete at the US Open from 18 June

Fourteen-time major winner Tiger Woods has said he will play more golf this summer to improve his world ranking.

Woods, the world number one a year ago, is now ranked 181 after finishing last of those who had made the cut at the Memorial Tournament in Ohio.

The 39-year-old endured the worst round of his career on Saturday, carding a 13-over-par 85 on day three.

"My back is good enough. I am fully committed to playing more golf all this summer," said the American.

Woods, who has played only five tournaments this season, said he would now start listening to his caddie, Joey LaCava.

"Joey keeps telling me this past week, 'take it easy on yourself, you haven't played much golf'," said Woods, who will play four times in under two months from next week.

"'You never played last year and you haven't played much this year. Tournament golf takes time'.

"I hate to say it when he's right, because as a player you always want to be right, but he is right."

Woods, who won his last major seven years ago in the US Open at Torrey Pines, is changing his swing.

He began working with consultant Chris Como seven months ago and said it would take time for the improvements to be implemented.

"I've had times like this in my life where I've gone through these periods, but you just have to fight through it," said Woods.

"I'm committed to what I'm doing and committed to the changes. Once I start to snowball and get more solidified, then that's when things start coming together.

"You just don't go from one to 10. We're taking it one, two, three, four... all the way to 10."
