Fan behavior on the PGA Tour was a point of contention in 2026.Several golf stars raised concerns during the season about the impact sports betting is having on the game, with the likes of Jordan Spieth and Matt Fitzpatrick speaking out.The Tour is making changes to its fan code of conduct in 2027GettyUS Open champion Wyndham Clark faced a very hostile crowd at Shinnecock Hills earlier this year, with fellow players later suggesting the reception could have been gambling related.Golf is highly susceptible to fans impacting on-course action, given their proximity to the stars inside the ropes.For 2027, the Tour will be making some changes, in a effort to prevent further disruption.PGA Tour rule changes coming for next season“We are concerned about fans interacting with our players in a negative manner, and certainly the potential for fans to try to impact the competition in some way,” Senior VP of tournament administration, Andy Levinson, said at the Tour Championship last week.Front Office Sports reports that the Tour is adding security measures to ‘better control poor crowd behavior’ during the 2027 season.Those measures include training volunteers to identify and report fans causing problems, while the fan code of conduct will also be revamped.“We’ve put a lot of effort into that,” Levinson added.“We have an ambassador program, which is a group of volunteers that is being trained to be amongst the crowds and look for certain types of behavior and then notify security.”While less than 5 percent of ejections at Tour events this year stemmed from sports betting-related incidents, Tour VP of gaming Scott Warfield believes even that number is too high.New programs are being created to help the organization track and monitor online commentary from fans about players they have bet on.Fan behavior at events in 2026 made plenty of headlinesGettyClark faced a hostile crowd en-route to a surprise US Open winGettyWarfield said: “One is one too many for us.“It’s why we spent the summer talking to players getting their feedback on this, leading to some of the stuff we’re looking at for 2027 with the tracking of harassing comments that usually start on the course, go online, or vice versa.”Beyond Clark’s ‘moronic’ reception at the US Open and gambling-related issues, general fan conduct has been in the spotlight in recent years.At the WM Phoenix Open in February, controversial streamer Jack Doherty paid a fellow fan $100 to shout during a Mackenzie Hughes backswing.The Tour admits fan behavior has ‘deteriorated’ in some marketsGetty“We are trying to take as many steps as we can,” Levinson said of general behavior.“At the same time, if you’ve got 10,000 people standing around a green and somebody decides to blurt something out, those things are really hard to control.“So, we do rely on decorum a little bit at golf tournaments. In some markets we’ve seen that deteriorate.”
