SCOTTSDALE, Ariz. (AP) - PGA Tour players and caddies have spent the first part of the season sorting out golf’s new rules.

The confusion continued at the Phoenix Open.

Among the new rules, caddies are no longer allowed to stand behind players as they line up shots not on the green. In Friday’s second round, Denny McCarthy was initially assessed a two-shot penalty after his caddie briefly stood behind him to discuss a shot at No. 15. McCarthy did not address the ball and backed off to line up his shot after his caddie stepped away.

The PGA Tour , with support of the USGA, reversed the penalty Saturday following a review of the interaction, changing McCarthy’s 67 to a 65. He was 8 under after a third-round 71.

“If he was in there deliberately looking at where I’m lining up and I’m setting up to the ball and not backing away, yeah, I could see how that’s a two-shot penalty,” McCarthy said. “But in no way, shape or form did I think what I did was a penalty.

A similar situation with Justin Thomas and his caddie in the second round also was deemed not to be a penalty. The USGA said in a statement the rule will be enforced similarly going forward.

“We saw the video many, many times and we just felt like we needed to look at it a little more with the interpretation,” PGA Tour rules official Slugger White said. “It’s a new rule. We agree with the rule, it’s just the interpretation is a little difficult now.”
