American Brandt Snedeker is at a career-best fourth in the world after following up back-to-back runner-up finishes with victory at the Pebble Beach Pro-am. While Shane Lowry looks set to face Rory McIlroy in the Accenture Match Play Championship in Arizona.
Snedeker relegates Justin Rose and Louis Oosthuizen to fifth and sixth respectively on the new rankings, while Richard Sterne's seven-shot win at the Joburg Open moves him up from 94th to 55th and into the field for next week's Accenture Match Play Championship.
The top 64 qualify for the first of this season's world championships, but Phil Mickelson is expected to reject his spot for the second year running - he has reached the quarter-finals only once - and that leaves Ireland's Lowry waiting for confirmation that he is the last man in.
Lowry is 0.0002 ranking points ahead of Swede Fredrik Jacobson, who needed to be seventh on his own at Pebble Beach to earn a Match Play place, but finished in a tie for seventh when American Patrick Reed holed from nearly 12 feet on the final green.
The seeded draw is not made until the rankings are updated again next Sunday night, but as things stand Lowry would face world number one McIlroy in the opening round and Rose would be up against Scot Richie Ramsay.
