Phil Mickleson would be the bet,but his wrist injury has put paid to that bet.
Vijay Singh is the man im pinning my hopes on,hes doing well in the averages,rank 12th for putting 12th for eagles a good stat when you got to play the 4th which is 607 yrds,although the 667 yard par 5 is probably not reachable in 2 shots,5th in birdies and 2nd in scoring averages.20's is a fair price.
