The rise and fall...
Jim Furyk's victory in the Chevron World Challenge on Sunday returned him to the top 10 in the World Ranking (jumping him from 11th to sixth), while Adam Scott's win in the Australian Open returned him to the top 50 (from 54th to 34th).
At the other end of the performance spectrum is David Duval, once the No. 1-ranked player in the world, who stands tied for 107th in the final round of the PGA Tour Qualifying Tournament and will not retain his tour playing privileges in 2010.
