There could be an historic moment when The Masters finishes at Augusta National with 48-year-old Kenny Perry in a share of lead going into the final round. Thirteen years after he lost a play-off for the US PGA to Mark Brooks at Valhalla – the course where he helped America to victory in last September&aposs Ryder Cup – Perry can now become the oldest champion in major history. He is two months older than Julius Boros was when he captured the 1968 US PGA title. With 18 holes to play Perry, round in 70, is joint leader with Argentina&aposs 2007 US Open champion Angel Cabrera, who broke 70 for the third day running with a 69. On 11-under, they are two ahead of Perry&aposs fellow countryman Chad Campbell, with Jim Furyk and Steve Stricker, two more members of Paul Azinger&aposs Cup side, lying fourth and fifth. Geoff Ogilvy remains the best placed Australian at two-under in a tie for 22nd place, one shot ahead of Aaron Baddely after the pair both shot 73s in the third round. Stuart Appleby shot a one-under-par round of 71 to move up to even-par and a share of 32nd place, while Robert Allenby is a shot back in a tie for 37th. The final round will see Tiger Woods and Phil Mickelson go head-to-head as so many people hoped. But they are joint 10th and seven shots back. After a nightmare nine on one hole in his third round 73, Padraig Harrington has accepted he is no chance to lift the trophy. No third successive major. No &aposPaddy Slam&apos of all four. Not this time any way. Harrington did not hesitate to write off his chances after his nine – only one short of the record high score at the 575-yard hole in Masters history. Although the Open and US PGA champion came back with five birdies he knew it was never going to be enough after starting the day already seven adrift. His pulled drive ran down a slope into trouble and in trying to get down near the green on the par five Harrington hit a tree trunk and rebounded into the bushes. He was forced to take a penalty drop, but his next attempt also hit a tree and went into a ditch. Despite the overnight tornado which had dumped over an inch of water on the area in under two hours he was able to play the ball out, but could not advance it far at all. His sixth was just short of the green and by failing to get up and down he crashed to two-over. “Obviously my chances went then,” he said after coming back with five birdies, but also after dropping two more strokes. “These things happen in the game and you can&apost do much about it.” “I didn&apost really think the second shot was a gamble, but there was a root in front of the ball and as I went to hit I backed off a bit.” “I wasn&apost concerned about the tree until then, but it came off the club a bit right.” “I&aposm not really disappointed and I was not deflated at all. It was a &aposso be it&apos sort of thing. I would not in any way say I have full control over my destiny.” “It wasn&apost to be. It&aposs the nature of the game – my game any way. I&aposll build up to the US Open now.” “I&aposm really gutted about how I chipped, though. I&aposm really not happy about that – you can&apost afford to give shots away and there were three easy ones I made a dog&aposs dinner of.” Woods birdied three of his last six holes, but he had opened with a double bogey six and that meant &aposonly&apos a 70 and at four-under par – three better than Harrington – he remained part of the chasing pack. Perry and Campbell were joint halfway pacesetters and both had two birdies in front nine 34s before the former edged in front on the next. Bogeys on the next two from Perry handed the advantage to Campbell as both continued their pursuit of a first major, but they were back on terms when Perry two-putted the long 13th. Campbell was the one to make the big error, though. He found the bunker right of the 16th, left it in and then missed from five feet for a double bogey five. But as that happened Cabrera, having birdied the long 15th, added another from nine feet at the 17th to catch Perry. Alongside Harrington on one-under are Justin Rose (71), 51-year-old Sandy Lyle (73), Graeme McDowell, who shot 73 playing with Woods, and Sergio Garcia, whose disappointing 75 will surely result in his wait for a first major continuing.
