In the space of two weeks, South African Branden Grace went from No. 258 in the world to inside the top 100. By notching his second European Tour victory in as many weeks at the Volvo Golf Champions, Grace moved up to No. 92 in the Official World Golf Ranking.
Grace defeated Ernie Els and Retief Goosen in the playoff at Fancourt, denying both players a spot at the Masters with the win. Each pulled closer, however, as Els improved 14 places to No. 57, while Goosen improved 16 notches to No. 45. Players inside the top 50 in the ranking at the end of Arnold Palmer Invitational will qualify for the Masters.
Mark Wilson improved 17 places in the ranking to No. 40 with his win in the wind-swept Humana Challenge. Since the start of the 2011 season, Wilson is tied for the most PGA Tour wins with Steve Stricker, ranked No. 5 this week.
The top seven players in the world were unchanged this week, with Luke Donald leading Lee Westwood by 2.26 points. Masters winner Charl Schwartzel, however, passed Dustin Johnson for the No. 8 spot after Johnson withdrew from Humana.
Tiger Woods, who begins his 2012 season this week in Abu Dhabi, remained at No. 25 in the ranking.
