The world golf number one Tiger Woods has won a record seventh WGC-Bridgestone Invitational title in Ohio, overhauling Padraig Harrington with a sizzling burst of scoring before benefiting from a late collapse by the Irishman.
Woods fired a five-under-par 65 to clinch his 70th PGA Tour victory by four strokes.
After starting the final round three shots behind Harrington, Woods took control by covering the front nine in a sizzling five-under 30 on the way to a 12-under total of 268.
Harrington, who had led for the first three rounds, regained a one-stroke cushion with three holes to play before his title bid unravelled with a triple-bogey eight at the 16th.
A closing 72 earned him a tie for second with Australian Robert Allenby (66).
