Today, both the R&A and USGA agreed on the banishment of the Anchored putters after the announcement of Rule 14-1b. The new Rule will not come into action until 1st January 2016.
The rule 14-1b was proposed to governing bodies in November 2012 and after a large review, an agreement between the USGA and R&A has been reached. There was a mixed view on the proposal; the European tour committees strongly supported the banishment of anchoring whilst the PGA tour and PGA of America were opposing the ban. Therefore, rumours had spread that different rules would be in effect in different tournaments.
In recent times, winners of major competitions have used these anchoring putters, such as Open champion Ernie Els, US Open champion Webb Simpson and recent 2013 masters champion Adam Scott.
