June 4th 2012, U.S.A.: Tiger Woods is up to fourth in the world after producing one of the shots of his life en route to winning the Memorial Tournament.

A spectacular chip-in birdie from the rough over the 16th green helped the 36-year-old to match the 73 PGA Tour wins of tournament host Jack Nicklaus. Only Sam Snead with 82 is ahead of him now.

The former world number one climbs from ninth to fourth a week before he heads to San Francisco for his attempt to win a 15th major. He is currently four behind Nicklaus' record - and has been since the 2008 US Open.
