When Bob MacIntyre stepped onto the lush greens of Augusta National earlier this week, expectations were high for a strong performance in his quest for the coveted Green Jacket.

Having displayed impressive form in recent tournaments, including The Players Championship and the Texas Open, MacIntyre seemed poised to make a serious bid for his first major title. Many believed his game was headed in the right direction.

The start of his opening round appeared promising, as he quickly moved to one-under par within the first three holes. However, things soon unraveled in a dramatic fashion.

MacIntyre ended the day an unexpected eight-over par, a crushing blow that all but extinguished his hopes of making the cut following a second-round 71. The Scot’s campaign at Augusta seemed doomed.

Yet, it was not just his score that sparked conversations. MacIntyre’s frustration boiled over during the first round, leading to multiple instances where he slammed his club into the ground and even made a rude gesture toward the pond on the 15th hole, actions that drew significant criticism.

The incident on the 15th was perhaps the climax of his struggles, as he sent the ball into the water twice. However, there were numerous other moments that added to the drama of his challenging day on the course.

It got to a point where Sky Sports repeatedly had to apologise. ‘Jesus, f***,’ raged MacIntyre after one errant shot. ‘F****** w*****,’ after another.

Maybe a bleep machine would have been best. Or to show MacIntyre’s coverage on a five-second delay. It certainly did him no favours.

Let’s not be sanctimonious about it. MacIntyre is not the first golfer to lose the rag and utter a few expletives. He won’t be the last either. But his meltdowns are becoming more pronounced and more concerning.

The swearing is one thing. But to be slamming his clubs into the ground and hacking up chunks of turf is quite another. That’s inexcusable.

Bearing in mind, MacIntyre’s dad, Dougie, is a greenkeeper. How would his old man react if he saw someone behaving like this back home at Glencruitten?

To lash out and damage a golf course like that is the height of ignorance and disrespect. Watching it all on TV, it was pretty embarrassing.

MacIntyre gets a lot of praise. He’s Scottish, he’s passionate, and he’s supremely talented. We all root for him in these big events. Of course we do. Just the same as we rooted for Andy Murray back in the day.

But personal sentiment and national pride do not make MacIntyre immune to criticism. That’s just not how this job works.

None of this is new to MacIntyre. His tantrums and hot-headed nature is not something he has ever sought to conceal.

At The Open Championship last year, he was asked about how he deals with setbacks and disappointment whenever he has played poorly.

‘I can go as mental as I want for an hour [after my round] and then after that, just back to life,’ he said. ‘You can break things. Literally do whatever I want for an hour. After that hour is gone, my job’s done.

‘I think it’s fair game to lose the plot every now and again.’

It was almost as if he revels in the volatility. Like he views himself as having an angry alter ego, almost like the Scottish Tyrrell Hatton.

But, in terms of what happened yesterday, this wasn’t after his round. This was on the course, in full view of the watching world. It was a monumental implosion.

When MacIntyre snapped his putter during the Sony Open in January earlier this year, he paid a heavy penalty.

‘My attitude cost me this golf tournament,’ he reflected. ‘I can’t be allowing that. My attitude has got to be spot-on for 72 holes.’

And that’s the point. Things don’t appear to be getting any better. If anything, his temper is getting worse, to the point that it is consuming him out on the golf course.

MacIntyre became a father earlier this year. Elite sportsmen will often talk about how fatherhood brings a more mellow side to their character. It gives them a greater sense of perspective.

But he continues to run extremely hot. The concern with MacIntyre is that his poor temperament will undermine his world-class ability.

Look at the top players across any sport. The vast, vast majority of them are able to enter an almost zen-like state in the heat of battle.

When they make a mistake, they brush it off almost instantly and move on. Whereas, with MacIntyre, too often he compounds one error with another. It’s a glaring mental flaw in his armoury.

Golf is different to other sports. If a tennis player smashes their racket in between points, they pull out a new one and they move on.

If a footballer wants to argue with a referee over a decision, they can do so. If they are playing poorly, there’s always a chance to make amends, a chance that their team-mates will bail them out.

Mistakes in golf are more pronounced. The punishment can be instant and savage. One bad hole can prove to be a card-wrecker, as was the case with MacIntyre at the 15th.

The tournament officials at The Masters invariably take a very dim view of this stuff. It was no surprise that MacIntyre was given an official reprimand and spoken to about his conduct.

The crux of the problem is that MacIntyre almost seems to normalise his volatility. It was evident when he spoke at Royal Portrush last year about ‘going mental’ and smashing things up for an hour.

Unless he can conquer these mental demons, they could undermine his immense talent. He must realise this himself.

Elite sport is about emotional maturity as much as it is about technical skill. You either learn to tame the beast within, or you let it consume you.

As written in these pages earlier this week, the parallels between MacIntyre and Murray are now unavoidable.

Murray possessed enough raw talent and natural ability to frequently get himself into contention to win Grand Slams. He was a regular in finals and semi-finals.

But it was only when he started working with his coach Ivan Lendl that he was able to take the next step and actually get over the line.

‘He [Lendl] has made a really big difference to Andy in terms of the emotional control on the court. I think that’s helped Andy to play his best tennis for longer periods of time. We all owe him a lot.’

The words of Murray’s mum, Judy, shortly after he had won his first Wimbledon title in 2013.

This is the crossroads at which MacIntyre now finds himself. Nobody doubts his natural talent. He is a proven winner and now ranked inside the world’s top 10 players.

But if he is to take the next step and win majors, it’s hard to see how that happens without him winning the battle inside his own head first and foremost.

The damage at this year’s Masters was done yesterday. From that point, he needed a miracle to make the cut. Any thoughts of a comeback were dynamited by a double bogey on his very first hole today. In the end, a seven-over-par halfway total meant he was destined to miss out on the weekend.  

But the vast expanses of Augusta were no more of a problem than the six inches between his ears.
