AKRON, Ohio: Tiger Woods criticized rules officials at the WGC-Bridgestone Invitational on Sunday after he overhauled Irishman Padraig Harrington to win the elite tournament for a record seventh time.

The American world No 1 effectively sealed victory with a birdie at the par-five 16th, where he struck a superb eight-iron to a foot after he and Harrington had been put on the clock for slow play.

Harrington's bid for a first title in 12 months on either the PGA or European tours unravelled on that hole as he ran up an ugly triple-bogey eight after hitting his fourth shot into water.
