Bradley switched to a 41-inch putter that is not anchored on Thursday and delivered an opening-round 67, which was one shot out of the early lead, thanks to 28 putts.
“I was disappointed with my finish at the (Byron Nelson Championship), putted really poorly,” said Bradley, who tied for 29th at the Nelson. “So I talked to mom after that and she said, ‘You’re not going to like this, but I think you should use the short putter.’”
Bradley spent last week in south Florida using the shorter putter, which is the same model as his previous putter (Odyssey Sabertooth), playing 36 holes a day with Michael Jordan and put it in play during Wednesday’s pro-am.
The U.S. Golf Association and Royal & Ancient agreed last year to ban anchoring beginning in 2016.
“My original plan was to qualify for this year’s Ryder Cup team and then switch,” he said. “But it was constantly on my mind.”
