McIlroy on top of the world after Honda Classic victory March 4, 2012 -- Updated 2246 GMT (0646 HKT) Rory McIlroy wins Honda Classic tournament in Florida McIlroy will go to no.1 in the new world rankings Tiger Woods puts him under pressure after an eight-under 62 (CNN) -- Rory McIlroy kept his nerve in the face of a last day charge from Tiger Woods to win the Honda Classic Sunday and jump to the top of the world rankings. The 22-year-old from Northern Ireland finished with a one-under 69 for a 12-under total of 268 at the PGA National in Florida. The victory will see him leapfrog England's Luke Donald as no.1. 14-time major winner Woods showed he is still a force to be reckoned with after a closing eight-under 62. He finished his round by draining an eight-foot eagle putt on the 18th to set the clubhouse target on 10-under 270. World no.2 Lee Westwood also charged through the field on the last day with a 63 to finish on eight-under. McIlroy, under constant pressure from those ahead of him and playing partner Tom Gullis, had to wait until the eighth for first birdie of the day. He dropped a shot at the 12th, but retrieved it with a birdie at the next to give himself a cushion playing the "Bear Trap" holes of 15, 16 and 17. The U.S. Open champion duly completed that test in level par and he played safe on the 18th for a par-five to wrap up his third PGA tour title. The 43-year-old Gillis birdied the 18th to tie Woods for second, two back, for his best finish on the tour.
