PHILADELPHIA -- Darren Clarke won his first major championship in his 54th major appearance on Sunday at the British Open.
With the win, Clarke soared from 111th to 30th in the new world rankings. Clarke, who won earlier this year on the European Tour, became the sixth consecutive first-time major champion.
Half the top 20 changed positions from last week. However, the top-six were unchanged with world No. 1 Luke Donald followed by Lee Westwood, Martin Kaymer, Rory McIlroy, Steve Stricker and Phil Mickelson.
Dustin Johnson, who shared second with Mickelson behind Clarke, jumped five spots to No. 7 this week. That knocked Matt Kuchar and Jason Day down one notch apiece, while Nick Watney held steady at No. 10.
Graeme McDowell slid two places to 11th and Masters champion Charl Schwartzel was down a notch to 12. K.J. Choi was 13th again this week.
Bubba Watson and Paul Casey exchanged spots with the American up to 14 and the Englishman down to 15. Ian Poulter and Adam Scott remained 16 and 17, and were followed by Hunter Mahan and Robert Karlsson. Mahan jumped two places, while Karlsson dipped one.
Closing out the top 20 this week is Tiger Woods. The last time Woods was outside the top 20 was January 26, 1997, when he was ranked 22nd.
