DeChambeau is the defending champ in Dubai, but he looks a lot different in his return after an off-season that saw him put on some 30 pounds of muscle.
"Well, it's opened new boundaries that I never thought were possible, to be up front with you," DeChambeau told reporters in Dubai after a Friday 67. "I don't know necessarily how to control all of it yet, but I'm getting to the place where I'm starting to learn with driver what I need, under the gun, in certain conditions, a left-to-right wind, a left-to-right wind, to do and how to apply that power in a way that's going to keep me in the fairway and allow me to have more scoring opportunities. So it's a gigantic leap for me."
