Joint leaders Angel Cabrera and Kenny Perry will take a two-shot lead into the final round of The Masters at Augusta on Sunday.
Poulter and Westwood lead European challenge seven shots back
Angel Cabrera and Kenny Perry will head into the final round of The Masters at Augusta tied for the lead and with a two-shot advantage over the rest of the field.
Cabrera, the 2007 US Open champion, produced his third successive round in the sixties (69) to finish up at -11 and will be joined in the final pairing by Perry who returned a steady 70.
Perry is bidding to become the oldest-ever major champion and will beat the record of 1968 USPGA champion Julius Boros if he does claim the Green Jacket on Sunday evening, while Cabrera will hope that by becoming the first man to post four sub-70 rounds at Augusta he can secure his second major prize.
Chad Campbell, who started the day in a share of the lead with Perry, ended it two back after an untidy finish to his round, while Jim Furyk and fellow American Steve Stricker are in fourth and fifth on eight-under and seven-under respectively after both shooting 68s.
Shingo Katayama of Japan, South Africa's Rory Sabbatini and 2004 Open champion Todd Hamilton are locked together at six-under, a stroke ahead of Tim Clark, while Tiger Woods and Phil Mickelson - who are paired together on Sunday - are part of a nine-man group on four-under that also includes Anthony Kim and leading European contenders Ian Poulter (68) and Lee Westwood (70).
Tiger seven back, disaster for Harrington
World number one Woods again struggled with his putter and appears to have left himself too much to do to claim a 15th major victory - especially given that all 14 of his previous triumphs have come when he started the final round either tied for or in the lead.
Meanwhile, Padraig Harrington's hopes of a third consecutive major crown were all but ended by a disastrous quadruple-bogey nine at the second on Saturday which restricted him to a 73 that leaves him ten shots off the pace at one-under.
The Dubliner, who took an eight at the 15th two years ago, pulled his drive into a sunken, wooded area to the left of the fairway and his first attempt to get out clattered into a tree and dug deeper into trouble. He finally managed to blast out, but also failed to get up and down from just off the green as his hopes more or less evaporated on the spot.
Sergio Garcia also stands at one-under following a disappointing 75, while Rory McIlroy returned a 71 and sits at level-par for the tournament.
But it is Cabrera and Perry who will start Sunday in the box seat after both men maintained their solid form.
Cabrera's day did not start well with a bogey at the first, but he quickly responded with a birdie at the third and a neat pitch at the par-five eighth set up another which took him to within two of then leaders Perry and Campbell.
The Argentine closed the gap further with a three at the tenth and, after a scrappy bogey at 14, joined Perry at the top of the leaderboard after birdies at 15 and 17 - the latter courtesy of a superb approach to ten feet.
Wobble around Amen Corner
Perry was steadiness personified for the majority of his round but did endure a wobble around Amen Corner.
He was three-under for the day and out in front on his own at 12-under overall following a birdie at ten, but paid for an overly-cautious approach at 11 and a wayward tee-shot at the short 12th as he posted back-to-back bogeys.
A two-putt birdie got him back on track at 14 and he then parred his way home to remain at 11-under.
Campbell had not dropped a stroke and was on the same score by the time he reached the short 16th but found sand with his tee-shot and, having left his first escape in the bunker, missed a short bogey-putt as he surrendered two shots with a costly double.
He bounced back with an impressive birdie at 17 - a hole he bogeyed on both Thursday and Friday - but signed off with another bogey having hit the trees down the right with his drive on 18.
While certainly not out of it, Campbell now has his work cut out to emerge victorious on Sunday with the winner at Augusta having come from the final pairing in 17 of the last 18 years.
