I'll have to check out the layout, I think they lengthened Augusta to attempt to make it Tiger proof years ago. Add to it this is a A list field so it makes it that much harder.
They Tiger proofed it for 2006. Note that Zack Johnson won it in 2007. They are going to lengthen 13 but doesn’t look like it will be ready this year. They have plans to lengthen 5.
