LONDON: Vijay Singh rose two places to fifth in the world rankings issued on Monday after winning the PGA Tour's season-opening event in Hawaii.   
 
The Fijian, who turns 44 next month, shot a closing three-under-par 70 to finish two strokes ahead of Australian Adam Scott in the Mercedes-Benz Championship at Kapalua on Sunday.   
 
The 26-year-old Scott rose one spot in the rankings to a career-best third.
