PGA Tour opposes ban on belly putters from 2016
The PGA Tour has come out against the proposed ban of anchored "belly" putters from 2016 but is not saying yet what it will do if the ban comes into force.
Ruling bodies Royal & Ancient Club and US Golf Association want to limit the use of belly and broom-handle putters.
"We have to look if anchoring is good, bad or indifferent for the game and we have concluded it's not been negative," said PGA Tour commissioner Tim Finchem.
A three-month consultation period to discuss the move, which would outlaw the anchoring method where a player hinges a putter to a fixed point on the body, ends on Thursday.
The PGA Tour, professional golf's biggest and most lucrative tour, has already written to the governing bodies to voice its opposition to the proposals unveiled in November last year. If the Tour decides not to adopt the new rules, which are due to be introduced in 2016, the implications for the running of the game could be far reaching. However at this stage of negotiations nobody is sure what those implications are.
Asked what happens if the ban comes into force, Finchem added: "I don't know because we have, I think carefully and intentionally, avoided at this point getting into a discussion about that issue.
"We have not even begun that discussion. This is a very subjective area. Everybody has an opinion about it and we certainly respect everybody's opinion."
