Tiger Woods pledges more golf to boost world ranking
Fourteen-time major winner Tiger Woods has said he will play more golf this summer to improve his world ranking.
Woods, the former world number one, 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.
Luke Donald will tee it up at the US Open next week after coming through qualifying in Florida.
The former world number one has fallen to 66 in the rankings, meaning he was not guaranteed a place in the field at Chambers Bay in Washington, beginning on June 18.
But the 37-year-old was one of four players to qualify at the Bears Club in Jupiter, finishing joint top on four under after rounds of 72 and 68.
Donald may have been worried after an even par first 18 holes but he came to life in the afternoon, registering seven birdies and three bogeys to finish alongside fellow qualifiers Andrew Pope and amateur Jack Maguire.
