Jordan Spieth

My only focus after I start the putter away from the ball is keeping the back of my left wrist as fat as possible from start to finish. This is critical to keeping the putterhead and ball moving straight down the target line after impact. It's also how Rory Mcllroy squares his putterface, and obviously it works for him.

What cracks me up is people who think I don't take baseball seriously. It's the most important thing in my life. They don't know how hard it is for me to get a bad game out of my mind. I still can't, but I'm getting better.

From a good lie in the middle of a fairway bunker, I'll make the same swing as I do from an average fairway lie. I'll dig my feet in slightly and keep my lower body stable so I won't slip, but I don't change my club selection or setup. It's only when the ball is sitting down in the sand that I'll make some modifications.
