WATFORD (England), Oct 1: Tiger Woods eagled The Grove's 18th hole for a third successive day to increase his WGC American Express Championship lead to six strokes in Saturday's third round.

Woods rounded off his revival by holing from about 34ft on the last.

A round of four-under-par 67 took him to 19-under-par 194, with Adam Scott, who carded a flawless six-birdie 65.
