Singh came close to moving atop the rankings last week at The Honda Classic, but he missed a short par putt in a playoff loss to Padraig Harrington. Singh was eyeing victory at the Bay Hill Invitational before his second shot at the 18th found the water. Singh tied for second with Graeme McDowell behind champion Kenny Perry, but the runner-up finish was enough to lift him back into the top spot in the world.
