But the ominous factor for 18 of them was that Tiger Woods was the one leading the way following a simply stunning second-round 66 on the Doral Blue Monster course.

From four behind, the world number one and defending champion - also a winner the last two times he has played the lay-out - moved two ahead on seven under par.

And the 18 closest challengers know the usual outcome from this position. Woods goes on to win.

Victory today would be his 14th World Championship title in 26 starts.
