Tiger roars back to take lead

Tiger Woods took a one-shot lead into the final round of the Buick Open as the world No 1 shifted into top gear on Saturday, firing a seven-under 65.

After an erratic opening-round 71 left him eight shots off the pace and sparked talk of missing consecutive cuts for the first time in his professional career, Woods spectacularly hit back to top the leaderboard on 17-under, one shot clear of faltering American Michael Letzig.

Woods triggered a wild roar that rumbled across the Warwick Hills layout when he rolled in a 34-foot birdie on the par-three 17th to join Letzig at the top of the leaderboard.

It looked to be the way the third round would end until Letzig stumbled to a double-bogey at the 18th for a four-under 68, gifting Woods a one-stroke lead.

Australian John Senden, who held a two-shot lead overnight on Friday, struggled to a one-under 71 to leave him two back going into yesterday's final round.

It was the 50th time Woods had taken a lead into the final round. He has gone on to win the title on 46 of the previous 49 occasions.
