You can see a tornado coming from quite a distance. The Tiger Woods twister hit virtually without notice on the second hole Monday. Five holes later Vijay Singh’s ambitions had been mercilessly trashed by two eagles and two birdies. A three-shot lead had been turned totally on its head. And just in case his wily adversary had any ideas of a back nine comeback, Tiger killed it off by out-birdieing him on the 15th.

The Fijian must have wondered what hit him, and by the time he found out it was far too late.

So hats off to Tiger for a stupendous “five in a row", forged with a healthy dose of good fortune, but sealed with a final round of awesome authority. Basically he rediscovered his deadly putter at the same time Vijay lost his. The irony is that for all that, and some wayward approach work, Vijay had a pretty good round at -3.

But Singh wasn’t the only one not to spot the Tiger storm in time. The in-play market makers struck me as far too slow to react to Tiger’s charge - you could still lay Vijay for around 1.7 as Tiger was clearly laying into him on the second hole. Not that I’m knocking their tardiness - it got me out of jail.

But another victory for the Tiger backers leaves you wondering when it’s going to be safe to lay the great man again.
