Luke Donald has climbed into sixth place in the world rankings ahead of the US Open at the Merion Golf Club in Pennsylvania.

The 35-year-old Englishman moves above American Brandt Snedeker while the top five remains unchanged ahead of the second major championship of the year.

Tiger Woods, Rory McIlroy and Adam Scott lead Matt Kuchar and Justin Rose at the top of the rankings.

Italy's Matteo Manassero won the PGA Championship at Wentworth to reach 25th place while there was significant progress for both Thomas Bjorn and Harris English.

The Dane moved 14 places up the charts to reach 73rd despite missing out on victory at the Lyoness Open to Joost Luiten, who enters the top 100 to take 96th place from Jonas Blixt.

Dutchman Luiten carded a closing 71 to finish 17 under par at Diamond Country Club, two shots ahead of Bjorn.

English's triumph at the St Jude Classic in Memphis, meanwhile, saw the 23-year-old jump from 139th to 84th.

The American birdied 16 and 17 to finish 12 under and keep a charging Phil Mickelson - who remains 10th in the standings - at bay while Scott Stallings' challenge faltered with a bogey on the 18th hole.
