There are any number of ways to measure success in professional golf. Major championships count for a lot, as do total victories and selection for The Presidents Cup and Ryder Cup teams. But since its inception in 1986, the Official World Golf Ranking has emerged as an important consideration. This year we look at the PGA
TOUR members who ended last season ranked in the top 20. This list does not include players like No. 1-ranked Lee Westwood, who supplanted Tiger Woods after 281 weeks atop the ranking, or PGA Championship Martin Kaymer, who, although ranked in the top 10, only plays on the PGA TOUR occasionally.
