​SOUTHPORT, England — Player conduct on the golf course has long been part of the Rules of Golf. This is the first time all four majors published their code for the players, and there already have been ramifications.Sergio Garcia was given a warning at the Masters when he smashed (and broke) his driver twice into the ground and then against a table holding a water cooler.AdvertisementAdvertisementAdvertisementThe USGA opted to bypass the warning and give Joaquin Niemann a two-shot penalty in the first round of the U.S. Open for heaving his wedge on his 15th hole (No. 6) at Shinnecock Hills after twice driving out of bounds and then hitting into thick rough. There were no spectators anywhere near where the club landed in the dunes.The two-shot penalty turned his 9 into an 11 on the hole and he shot 78. He still tied for seventh.Is it working?Jon Rahm, who describes himself as an “intense” player, doesn’t mind the code of conduct. His only question is who it gets applied. Because while the principles and penalties are similar at the four majors, it’s at the discretion of each one how it gets applied.AdvertisementAdvertisementAdvertisement“I think it’s good. I get it,” Rahm said. “They have a code of conduct and they enforce it. Why not? It’s not going to change how I play. To go from zero to a penalty? I don’t know.”The R&A’s conduct policy reads: “If a player’s (or their caddie’s) behavior is so far removed from what is expected in the spirit of the game of golf, in accordance with Rule 1.2b, the Chief Referee, in consultation with the Chief Championships Officer, may issue an official warning or apply a penalty of two strokes or disqualification, taking account of the frequency, impact or potential impact, intent and severity of the misconduct. An official warning does not need to be given prior to applying a penalty of two strokes or disqualification.”Rahm was playing with Garcia when he lost his temper in the final round at Augusta National. He still doesn’t know exactly what happened with Niemann. But his views on the policy made him wonder why this was getting more attention than pace of play.“Sergio received a warning. I think Joaco maybe deserved a warning — I don’t know what he did,” Rahm said. “With all the policies we have on pace play, you get a warning, another warning and then you MIGHT get a penalty.”AdvertisementAdvertisementAdvertisementRahm suggested a warning was warranted on the first offense, especially in the first round.GOLF-LIV-AUSA major that travels? Rahm interested in taking golf’s biggest events to other parts of the worldJon Rahm told reporters ahead of the Open Championship at Royal Birkdale he believes golf would benefit from having a major championship that travels.
