Golf: Sizzling Tiger opens four-stroke WGC lead at Doral

Tiger Woods fired seven birdies, the last of them a 16-footer at the final hole, on his way to seizing a four-stroke lead after 54 holes Saturday at the World Golf Championships Cadillac Championship.

World No. 2 Woods, whose 24 birdies through the first three rounds is a personal best for any PGA event since he joined the US tour in 1996, fired a five-under-par 67 to match the day's lowest round and stand on 18-under-par 198.

Northern Ireland's Graeme McDowell, playing alongside Woods, eagled twice in the same round for the first time in his career on his way to a 69 that left him on 202 and partnered with Woods in the final round as well.

Phil Mickelson and Steve Stricker shared third on 203 with South Africa's Charl Schwartzel, Spain's Sergio Garcia and Americans Michael Thompson and Keegan Bradley sharing fifth on 205.
