MEMPHIS (Tenn.) -- As if Bryson deChambeau hadn't had enough to do these days.Two European Tour pros called out the eight-time PGA Tour winner on Twitter for failing to yell, "Fore!" in the last two days. After hitting an error on the WGC-FedEx St. Jude Invitational tee shot.Screaming "Fore!" This is a common practice that warns spectators that a ball could be coming to them and encourages them to run for cover.Richard Bland (48), an Englishman who led the 36-hole U.S. Open leader this year and had earlier won his first European Tour event at The British Masters, was harsh about DeChambeau's performance on Thursday. This was a day DeChambeau hit 11 fairways and shot 65."Bryson plows it into the crowd once more off the tee, & there is no shout of "Fore." Perhaps it requires someone to be seriously injured to teach him.Edoardo Molinari (40), a three-time European Tour winner, is also upset. He is the older brother to 2018 Open champion Francesco Molinari. DeChambeau was also seen on DeChambeau's 18th hole tee.Molinari tweeted, "It shouldn’t be hard to understand that you should always shout "fore"' when you hit an shot into the crowds," "When will someone do something about it?" "Hopefully before a spectator gets hurt!"Bland and Molinari are not in the WGC field. They commented on it after they had seen it on television.DeChambeau isn't the only one to be called out for it. This is a common source of irritation within the game. It was brought up at The Open last October when DeChambeau was asked about his behavior in a pre-tournament conference."I do shout fore,'' DeChambeau said. "I don’t know what you’re talking about. There are many people on the tee boxes that shout fore. This is a controversial topic, which is unfortunate. However, 99 percent of the times I do shout fore, and unfortunately, people believe I don't. They can say what they like.(It's also fair to mention that DeChambeau or other pros might not hear their cries from 350 yards away. The idea is that other players will shout the warning when DeChambeau does.DeChambeau did not answer questions about it after Friday's round at TPC Southwind, where he tied for seventh place, four shots behind Harris English, who was playing 4-under-par.DeChambeau has had a difficult few months. To ruin his chance of defending his title, DeChambeau shot 44 over the last nine holes at U.S. Open. He also split with Tim Tucker at the Rocket Mortgage Classic, and then missed the cut. At The Open, he claimed that his driver was "sucks" and partially blamed the club for a disappointing first round. Only to have Cobra, his endorser and equipment manufacturer, publicly criticize him for his comments.DeChambeau was found to be positive for COVID-19 two weeks ago. This knocked him out of the Olympics.TPC Southwind earlier this week, he spoke out about his COVID-19 woes and admitted that he hadn't been vaccinated. He mistakenly believed that there weren't enough vaccines.He said, "I'm too young to give the vaccine to anyone who needs it." I don't require it. I am a young, healthy person who will continue to improve my health. I don't believe that taking the vaccine from someone who is in need of it is a good idea.According to the Centers for Disease Control and Prevention, there is no shortage of vaccines in the United States.DeChambeau, who admitted that he had lost between 8 and 10 pounds during COVID-19 recovery, was subject to a lot of backlash.Louis Oosthuizen will be his partner in the WGC-St. Jude Invitational's third round. He starts at 1:30 p.m. ET.
