Arnold Palmer Invitational round three: Will Bay Hill Singh to Vijay's tune?

Talk about meltdown. The really odd thing about the third rounds of playing partners Rocco Mediate and Paul Casey Saturday was that their games got worse as the weather got better. Health problems? Did Mediate’s back perhaps send him few reminders? Casey apparently was complaining of being ill before starting his round.

So a hugely different leaderboard greets us on day four. The wind and chill factor was a surprise Saturday and we may be in for more. Tom Lehman says it’s the northerly wind that is making things so difficult, and that’s what we look set for.

Despite his two-stroke lead, I’m not excited by Vaughn Taylor, especially given his poor record for closing out tournaments. Ben Curtis on the other hand has an excellent record when he has a sniff of victory. And then, of course, breathing down their necks is a past-master at final round charges, Vijay Singh.

There’s plenty to impress right down to four under and beyond, although I’d shy away from Shaun Micheel, whose driving is not so hot, and Sergio Garcia, who still struggles with the putter (Jerry Kelly likewise). There’s still a vague threat from Tiger Woods, but I stick with opposing him.

Anyway, I’m banking on a shifting in-play market to provide my entertainment. If I had to pick a winner at the point of a gun I’d say Singh. He knows how to get things done on a Sunday and to do it in the same field as Tiger would be an especial bonus. I’ve also got a sneaky feeling, though, that Curtis might pull off another surprise.
