Ian Poulter and Nick Faldo both hit final rounds of 69 to end at six under.
Only an unlucky bogey at the 17th, when the ball trickled down off the edge of the green, spoiled Poulter's card.
"I should be winning these tournaments now and I'm not happy - I am disappointed that I didn't finish the job off," said Poulter.
Meanwhile, Faldo played the final two holes superbly - with massive putts earning him a birdie and an eagle - to salvage an otherwise mediocre round.
Faldo admitted he was mystified by the sudden return of his putting prowess at Sunday's final two holes.
Brilliant putts at the 17th and 18th made a mockery of Faldo's four rounds of struggle on the greens.
"I walked behind the pin at the 18th and thought 'I fancy this' - I haven't fancied a putt all week," Faldo told BBC Sport.
"How did it happen? I hit it perfectly sweet and it never looked like going anywhere else.
"It's been a long, hard week but it's been a great week and I've loved every minute of it."
Simon Dyson ended his steady campaign with a 73 for a two-under total and a share of 34th place.
Fellow Englishman Simon Khan carded a 70 to finish on one under and a highly-creditable joint-equal 41st place.
Luke Donald's promising challenge trailed off with his poor third round, and a final-round 70 saw him finish back in the pack.
Donald became the latest player to suffer at the hands of the infamous 17th at St Andrews, with a double bogey.
Donald failed to carry his fine early form into the closing rounds
"It was disappointing, extremely disappointing," he said.
"I'll have to look and see what the problem is when it comes to majors. I keep throwing in a big number."
The 27-year-old admitted the honour of playing alongside Jack Nicklaus in the opening two rounds could have had an adverse effect.
Nicklaus was playing the final Open of his illustrious career and attracted huge galleries and a rapturous reception over both days.
"It might have affected my energy levels a little bit," said Donald.
"To be subjected to that much emotion, all the crowd's energy (is difficult), but I should be strong enough to not let that affect me."
