The two-time U.S. Open champ is teeing it up at the VidantaWorld Mexico Open, where he'll be without his regular caddie who is at a wedding. But Clark is more focused on another upcoming wedding: his brother's. And with his younger brother Brendan filling in on his bag, it's a chance for Big Bro to do him a solid. "I would love for my brother with his wedding coming up a great week so I can give him a nice check to help pay for the wedding and honeymoon," Clark told reporters on Wednesday.

In any event, here are Golf Digest's expert picks for this week's tournament.
