The Royal & Ancient Golf Club and the U.S. Golf Association adopted Rule 14-1b, which prohibits players from anchoring a club against their bodies.
"We strongly believe that this rule is for the betterment of the game," said USGA President Glen Nager. "Rule 14-1b protects one of the important challenges in the game -- the free swing of the entire club."

The decision Tuesday ends six months of sometimes rancorous debate. The rule was opposed by the PGA Tour and the PGA of America, which contended the stroke commonly used for long putters was not hurting the game and there was no statistical proof that it was an advantage.
"We recognize this has been a divisive issue, but after thorough consideration, we remain convinced that this is the right decision for golf," R&A Chief Executive Peter Dawson said at European Tour headquarters outside London.
The next step -- and perhaps the most important step -- is for the PGA Tour to follow the new rule or decide to establish its own condition of competition that would allow players to anchor the long putters. Most believe that would lead to chaos in golf. If a special condition were allowed for the PGA Tour, it would mean players could not use the anchored stroke at the U.S. Open and British Open. Augusta National is likely to follow the new rule at the Masters.
