Miguel Angel Jimenez was among those to make good progress as the closing round of The Masters Tournament got underway.
The Spaniard was among the earlier starters on a glorious day at Augusta National and birdied three of his first nine holes to move to level par for the tournament, 12 adrift of leader Lee Westwood, who was just about to begin his final round.
England's world number four, making his 50th attempt to win a major, led by one from two-time champion Phil Mickelson, with the returning Tiger Woods and Korean KJ Choi three shots further back in a tie for third.
Just ahead of Jimenez was American Scott Verplank, who moved inside the top 20 on one under after picking up four birdies in his first 11 holes.
Former champion Trevor Immelman remained on two under after following a birdie at the second with a bogey at the short fourth, while Nick Watney was three under for his final round after seven holes, taking him to four under for the tournament.
Sixteen year old Italian Matteo Manassero, the youngest player ever in The Masters, covered the first 11 holes in one over to be five over for the tournament.
Manassero, who makes his professional debut next month, was joint 38th, which was matching the position Sergio Garcia achieved when he was the last British amateur champion to survive the halfway cut.
You have to go back to 1937 and the fourth Masters for a better performance than that by a European amateur. England's Francis Francis was 28th that year.
Garcia, meanwhile, had dropped to nine over for the tournament as he approached the closing stages of his final round.
The crowd at the short 16th did not have to wait long to witness the 12th hole in one there in Masters history.
Australian debutant Nathan Green became the 12th player in the history of the tournament to ace the hole - and it followed another eagle from him at the long 13th.
The blows did at least enable Green to end on a high note. He shot 80 in the third round and had just triple-bogeyed the short 12th to go to 17 over par.
Eventually the 34 year old finished with a 75 for 14 over, but his name was now in the record books.
Padraig Harrington and Ian Poulter are among the other 11 to have holed-in-one on the 16th, where the pin was in its traditional Sunday position of back left.
In contrast, there has only ever been one ace on the fourth - by Jeff Sluman in 1992 - four on the sixth and three at the 12th.
