HUMBLE, Texas — Adam Scott is back at the Shell Houston Open for the first time in seven years with a change in strategy for the majors.

He wants to make sure his game is up to speed for the Masters.

And that goes for his caddie, too.

Scott has two caddies who are in a job-sharing program, and while Steve Williams usually works at the majors, Scott felt it was important for Williams not to go to Augusta National without having seen him play.

He also has been commuting from Australia, where his wife is pregnant with their second child.

“That almost made this become very easy for me to put on the schedule and change things up,” Scott said. “Part of my plan for the rest of the year is to play the week before the majors.”

He faces what has become one of the stronger fields of the year at the Golf Club of Houston, which tries to present a test that will get players ready for the Masters. Nothing compared with Augusta National, though the greens are faster and rough has been shaved to create tightly mown areas.
