Sandy Lyle carded his best round at Augusta for eight years when he completed his 26th Masters with a one-under 71 for a 15-over-par total.
Lyle played superbly for a man short of competitive golf
The 1988 champion holed some huge putts early on to get to three under through five and then mixed four bogeys with two more birdies over the next 13.
It was a great response from the 49-year-old Scot to five-putting the 16th on Saturday and slumping to an 80.
Lyle's decent round was an early sign that the course may be playing easier.
"The wind is not playing a huge factor today and the pins are a little fairer," said Lyle, who ended 14 shots off the lead.
"I'm not saying they're easy but I think you might find a lot lower scores today."
Three players succeeded in breaking 70 - the winner Zach Johnson and runners-up Rory Sabbatini and Retief Goosen carding 69s - while Jerry Kelly, Ian Poulter and Stewart Cink shot 70.
But Lyle was among a handful of players with the next best score of 71 and he served a warning that he could be a force on the Champions Tour when he becomes eligible next Ferbuary on his 50th birthday.
