Jordan Spieth's fore shout labelled 'criminal' during final round of CJ Cup Byron Nelson

Jordan Spieth might need a refresher on shouting 'fore'. 

At least that is the verdict of some golf fans after watching his 'criminally apathetic' warning to spectators during the final round of the CJ Cup Byron Nelson.

Spieth came into the PGA Tour event at TPC Craig Ranch hoping to build some momentum ahead of the second men's major of the year.

It's fair to say that Spieth will head into the US PGA Championship at Quail Hollow Club buoyed by his performance in Texas. 

Spieth vaulted up the leaderboard on Sunday afternoon, notching seven birdies in his first 13 holes to close the gap on Scottie Scheffler. 

But what transpired on the par-5 12th hole rubbed some viewers the wrong way.

Spieth knew straight away that he pushed his tee shot slightly right towards the cart path. 

But he didn't really send a clear warning. GOLF's Sean Zak clipped and re-shared the moment on X, describing it as the: "Mount Rushmore of apathetic fore calls."

Another replied: "That is criminal. Someone is going to get sued soon."

Watch the moment here:

In fairness to Spieth, he has never developed a reputation as someone that doesn't send warnings when he hits an errant shot. 

Several high-profile players over the past few years have come under heavy fire for not alerting crowds a golf ball is heading in their direction. 

Bryson DeChambeau, who recently claimed his third LIV title in Korea, came under particular scrutiny when he was playing on the PGA Tour.

DeChambeau claimed he did sending warnings. 

But it came with a caveat that sometimes it's 'safer' to say nothing at all. 

"Most of the time when we hit shots, if we don't think it's going to get there, there's really no reason to say anything and most guys don't on Tour," he previously explained on Rick Shiels' podcast. 

"You could, because of how far I'm hitting it [on] every single shot say, 'Fore'. Sometimes, it's potentially more harmful because people move and they walk into the direction of the golf ball. 

"When I see a ball and it's close but I don't think it's going to get to someone, that's when I'm like, one, they can't hear me because it's into the wind.

"I can yell as loud as possible, and they wouldn't be able to hear me. That's another thing. 

"People think that I'm not being respectful and that I don't care about patrons or people. That’s the farthest thing from the case. 

"I've hit people before and it's been the worst possible feeling in the world, so don’t ever think I don't care about fans."
