Woods moved up 12 places after breezing to a five-stroke victory Sunday at the Arnold Palmer Invitational in Orlando, Fla.
Luke Donald led the top five, which remained unchanged, while Masters champion Charl Schwartzel dropped one spot to seventh. Phil Mickelson fell two spots to 15th.
Woods closed with a 2-under-par 70 and eased to a comfortable victory over playing partner Graeme McDowell, giving him his first tour victory since winning the BMW Championship on Sept. 13, 2009 - a span of 924 days.
It was the 72nd PGA Tour win for Woods, whose last tournament victory came at the Australian Masters in November 2009 - two weeks before the car crash in his Florida driveway that led to revelations of marital transgressions and sent his career into a tailspin.
