Robert MacIntyre makes defiant vow after Open Championship warning

Robert MacIntyre has insisted he will not change his fiery on-course personality after receiving a code of conduct warning during the final round of The Open.

The Scot's hopes of challenging for the Claret Jug faded over the weekend as successive rounds of 71 left him tied for 28th on 2-under par after starting Saturday firmly in contention.

MacIntyre's frustrations boiled over on the 16th tee on Sunday when he slammed his driver into the ground, prompting officials to issue him with a warning.

Watch what happened here: 

Despite the incident, MacIntyre made it clear he has no plans to tone down his emotions, describing his reactions as simply "part of my DNA."

Speaking after his round, the European Ryder Cup hero said: "Yeah, I'm going to do it for the rest of my career. I try and toe the line, but when you feel like you're playing a golf course where you can hit it pretty much anywhere and there's no real punishment, then you hit one slightly off line and get the biggest punishment you can possibly get, it's a sore one.

"Again, I'm going to react aggressively at times. Part of my DNA."

The warning comes just months after MacIntyre attracted attention at The Masters when he made an obscene gesture during his round at Augusta National.

It also came two days after Jon Rahm also received a warning for losing his cool on day two at The Open. 

Bob MacIntyre thinks Royal Birkdale is a bad fit for him

Reflecting on his week, the 29-year-old admitted Royal Birkdale never quite suited his game, despite arriving believing he had a genuine chance of contending.

"Coming into this week I thought I had a really good chance," he said. "Even going out today, I thought I had a good chance. But the more I play that golf course, the more I realise it doesn't really set up that well for me."

MacIntyre also questioned the course setup, suggesting modern links venues increasingly favour the game's biggest hitters because wayward drives are not punished enough.

"There are certain holes where the longer hitters, the guys cruising it at 184 ball speed, are taking driver on and there's no punishment," he said. "I feel like that's the way professional golf is going.

"I get we're trying to get crowds in, but links golf needs gorse bushes. I'm watching the longer hitters bomb driver down nine and there's one gorse bush down the left-hand side.

"I feel like that's the way the new designers are going. So yeah, it wasn't to be my week. But there's always next year."

It completed another frustrating major campaign for MacIntyre, who missed the cut at both The Masters and the PGA Championship before finishing tied for 39th at the U.S. Open.
