As the US PGA Championship tees off in Pennsylvania, all eyes are on Robert MacIntyre—and not just for his golf game. The 29-year-old Scot, ranked world number 12, is chasing his first major title, but legendary countryman Colin Montgomerie has some sage advice: patience, not passion, may be the key.

MacIntyre came heartbreakingly close at last summer's US Open at Oakmont, finishing as runner-up. But recent form has been a mixed bag. He missed the cut at the Masters last month, and his on-course behavior at Augusta drew headlines for all the wrong reasons—a middle finger gesture toward the 15th green, a club slammed into the turf on the 17th, and a string of expletives picked up by microphones. It's a fire that burns bright, but Montgomerie, an eight-time European Tour Order of Merit winner, believes it might be burning a little too hot.

"It is the way he is," Montgomerie said. "There is fire in his belly and he wants to be good and better himself and win. That is important—not to lose that. But at the same time, that is forcing it. To force it, especially at Augusta or these majors where it is the ultimate test, is very difficult."

Speaking from Aberdeen, where he was promoting the Staysure PGA Seniors Championship at Trump International, the 62-year-old offered a gentle nudge. "If I am giving him any advice at all—and who am I to give advice?—I would love to say to him, 'Just let it happen, let it breathe, be patient and let it happen.' I am sure if he does that, success will come."

Montgomerie pointed to MacIntyre's stellar US Open performance as proof of what's possible when the game flows naturally. "After his fantastic performance at Oakmont, where he was a putt away from winning, I think he is probably trying a little bit too hard. So if he can just let it happen and let that talent shine through, he has every opportunity of winning a major. That would be great for Scottish and European golf."

The veteran's confidence in MacIntyre's game is unwavering. "The game is there—he can play. The green work is superb, the chipping and putting is superb. That is where it is won and lost."

For MacIntyre, the message is clear: harness the fire, but don't let it consume you. As he steps onto the course this week, the question isn't whether he has the talent—it's whether he can let success happen, rather than chasing it.
