Twenty years later, Phil Mickelson could have the same effect on drivers.

Using a unique mix called "draw" and "fade," Mickelson shot a final-round 3-under-par 69 to win his second green jacket in three years. He is believed to be the only Masters Tournament champion to carry two drivers.

"I'm sure there will be drivers sold left and right," Billy Mayfair said. "When Nicklaus won here with that big putter he used, everybody bought that big putter. So (today) everybody will probably have a hook driver and a fade driver in their bag."

Mickelson used a pair of Callaway Fusion FT3 drivers. His "draw" club is 9 degrees and 46 inches long; his "fade" driver is 9.5 degrees and 45 inches.

He put two drivers in the bag to help him fight the 155 yards added to Augusta National Golf Club.

"I call it a draw and a fade, but the fact is, the draw is like an additional driver; it makes my normal driver a 3-wood, because it goes so much farther," he said. "And I needed to combat the added length here at Augusta."

Mickelson decided to try the two-driver method in last week's BellSouth Classic. He blew away the field with a 13-shot victory.

The 35-year-old left-hander decided to take the same game plan into Augusta.

"Our new slogan at Callaway is the only thing better than an FT3 driver is two FT3 drivers," Mickelson said after winning the BellSouth Classic. "I knew I was going to do that at Augusta, after playing there on Monday and Tuesday, I decided there were too many shots off the tee where I needed different distances, and these drivers are different distances.

"All of the right-to-left holes, I didn't have to hit it very hard, and all of the left-to-right holes I had to hit it pretty far. I hit a driver I hit a long ways that draws, and I have a driver that fades and stays in play. I wanted a week where I did this before the Masters, to see if I could go from one driver to the other and still hit fairways and not have it be a big change."

Ultimately, Mickelson's idea worked. He led the field in driving distance this week (299 yards) even though he tied for 36th (of 47 golfers who made the cut) in driving accuracy.

"People kid about Phil, but he's one of the most intelligent persons I've been around," Mayfair said. "He's always thinking ahead. He's just a smart man. He's really worked his butt off to learn this golf course."

Mayfair played a Tuesday practice round with Mickelson. He asked about the two-driver novelty. Mickelson replied it was just for the Masters.

Now, Mayfair believes other people will copy Mickelson.

"Now you may see some more guys show up next year here with two drivers," Mayfair said. "Guys keep changing the golf course, and we keep thinking of ways that makes it easier for us to play."
