Padraig Harrington and amateur Paul Dunne saw their Open challenge fizzle out in the final round at St Andrews.
Harrington finished joint 20th on seven under after a three-over-par 75 while joint overnight leader Dunne slipped to a 78 and tied 30th on six under.
Former US Open winner Graeme McDowell carded a 70 in the weather-delayed major to end four under and joint 49th.
American Zach Johnson won in a play-off with Louis Oosthuizen and Marc Leishman after the trio finished 15 under.
Dunne was enjoying a fairytale tournament and went off in the final group alongside Oosthuizen.
A nervous start saw the Dubliner bogey the opening two holes but he recovered with birdies on three and five.
However, five shots were dropped on the difficult back nine as Dunne also missed out on the Silver Medal for best amateur.
"I was nervous but nothing anything different to the last three days," said the 24-year-old.
"But the last three days I got off to a steady start and settled into the round and on Monday I had a couple shots that I hadn't seen in any practice or any range sessions I've had.
"It kind of just rattled me a little bit. I didn't really know where they came from and I just never settled in after it."
Two-time champion Harrington began two shots off the pace and he shared the early lead thanks to three birdies in the opening five holes.
His hopes faded after a double-bogey at the sixth and he also dropped two shots at the tough 17th to go along with four bogeys.
The tournament marked a welcome return to form for Harrington, who had recorded just three top-10 finishes in the majors since winning the 2008 US PGA Championship.
"I felt very good mentally; not great on the greens at times but very good mentally up to a certain point," he said.
"Then the greens kind of got a bit to me. I hit lovely shots really all the way home. Only really that tee shot on 17 wasn't great but everything was pretty strong."
