Paul Casey's runner-up finish in the Nissan Irish Open has lifted him back into the world's top 50 just a week before the cut-off point for next month's US Open at Winged Foot.
Casey goes to 42nd in the new rankings, while winner Thomas Bjorn moves from 33rd to 30th.
Darren Clarke, who finished third at Carton House, remains the leading Irishman in the standings, moving up one place to 19th. Padraig Harrington (29th) and Paul McGinley (36th) are the only other Irish players in the top 50 with Graeme McDowell falling five places to 91st.
Lee Westwood and Paul Broadhurst, 52nd and 55th respectively, will try to claim a place in the top 50 at this week's BMW Championship at Wentworth. Should they miss out, they face a 36-hole qualifier for the US Open at Walton Heath in Surrey in two weeks' time.
American Tim Herron beat Swede Richard Johnson in a play-off for the US PGA Tour's Bank of America Colonial tournament. Herron leaps from 60th to 33rd and Johnson from 174th to 94th.
