Belly putter, what? Who needs that crutch anymore (especially with the USGA ban on anchoring coming into effect in less than a year)? Not Webb Simpson! — the 2012 U.S. Open champion is using a conventional length putter for the first time on the PGA Tour at this week’s Sony Open and it’s working pretty well for him so far. At the halfway mark, Simpson is 12-under and tied for a three-way share of the lead with Matt Kuchar and rookie Justin Thomas.
