Robert Allenby has just missed out on direct place in next week’s World Golf Championships Match-Play Championship and faces an anxious wait to find out if he will be included in the 64-man field.

Defending champion Luke Donald topped the qualifiers list released on Monday while 68th-ranked Allenby will have to rely on some of the top 64 players to drop out of the event for a place.

Allenby, who last week was ranked 64th, has suffered a minor slide in rankings as tournament wins for other golfers coupled with his 33rd place finish at the Phoenix Open earlier this month caused a reshuffle.

Spain’s Rafael Cabrera-Bello won the Dubai Desert Classic to jump from 119th in the rankings to 60th to qualify for his WGC debut while Belgian Nicolas Colsaerts shared ninth to jump from 69th to 64th to make the field, knocking Allenby onto the alternates list.

While the entry list is pulled from this week’s rankings, players have until Friday to confirm their spot in the field or drop out.

World No.1 Donald, who won the US and European money titles last year, led the field by virtue of his ranking with fellow Englishman Lee Westwood second, Northern Ireland’s Rory McIlroy third and Germany’s Martin Kaymer fourth.

If the European foursome hold their spots for another week they will be the top seeds in the four brackets to be released next Monday based upon next week’s rankings.

World No.11 Phil Mickelson, coming off a victory at Pebble Beach on Sunday, plans to play this week at Riviera and skip the WGC event, opening the way for the 65th-ranked player in the world, South Africa’s Ernie Els, to make the lineup.

Els was just ahead of 66th-ranked compatriot George Coetzee, who might also find his way into the lineup if England’s Paul Casey, ranked 23rd, skips the Dove Mountain event.

He is recovering from a shoulder injury.

Along with Allenby, other alternates waiting behind Coetzee for a spot in the lineup include 67th-ranked American Ryan Moore and Dutchman Joost Luiten ranked 69th.
