AUGUSTA, Georgia (Reuters) - Bryson DeChambeau said he is getting "super close" to finding the perfect driver head to suit his powerful game at this week's Masters, where he will look to build on his career-best finish at the tournament a year ago.

The two-time major champion got off to a hot start at Augusta National last year, carding an opening round 65 to take the 18-hole lead before finishing tied for sixth.
