Portrush, Northern Ireland (CNN)The roars for Shane Lowry were just different. Deeper, more throaty, more heartfelt.
With no Northern Irishman in contention, the Royal Portrush crowds have taken Ireland's Lowry to heart and how it has inspired him.
They roared and chanted and clapped and waved as he walked onto the 18th green Saturday, having left the field trailing in his wake on day three of the 148th Open.
It had been a truly masterful display, as the 32-year-old from County Offaly fired a stunning 63 to surge to 16 under and take a four-shot lead into the final day Sunday.
The world No.33 will play in the final group alongside English Ryder Cup hero Tommy Fleetwood, who shot 66, with American JB Holmes two further back at 10 under.
The bearded Lowry has missed the cut in his last four Open Championships, but he has tapped into a special source this week.
He grinned and shook his head as the roars punctuated the still Portrush air as he forged clear while the pack shuffled constantly behind him.
The Open hasn't been to these parts in 68 years and the local fans were determined to make the most of the occasion.
"That was the most incredible day I've had on a golf course," he told reporters with a twinkle in his eyes afterward.
"I just wanted to keep making putts to hear those roars."
At one stage he told his caddie Brian "Bo" Martin, who is from Ardglass, an hour or so to the south, to make the most of it.
