The trio are one ahead of defending champion Angel Cabrera of Argentina who, like Harrington, bogeyed the last hole after failing to get up and down from the bunker.

Overnight leader Harrington allowed the field to come back to him after scrambling to a round of 71 as he struggled to adapt to the damp conditions.

Scahill caught up six shots to earn a share the lead and equalled the course record with a glorious seven-under-par 65, while Casey was equally impressive with a 66.

"I struggled today," admitted Harrington.

"I struggled a lot off the tee. I will have to play a lot better tomorrow if I am to win.

And when asked who would be his biggest threat to winning the tournament in Sunday's final round, the Irishman had no doubts.

"Me," he said. "I am much more worried about myself than anyone else."

Scahill was delighted with his superb round - including seven birdies - which put him right back in contention for the title.

"That was probably the best round I have played, especially given the wet, cold conditions," said Scahill.

What a moment - it was unbelievable Simon Khan on his hole-in-one

"The hardest thing on Sunday will be the mental side of things. If I can control my mental state I can still be there at the end."

Casey began the day five shots back but a run of birdies on the back nine moved him into a share of the lead.

"I had my game plan and I stuck with it. It worked a treat," he said.

Colin Montgomerie failed to make an impression, spoiling two birdies with two bogeys, but Simon Khan can reflect on a successful day after winning a �36,000 car for a hole-in-one at the 12th.

"My only other hole-in-one was as an amateur at Wanstead - I got a pat on the back for that," said Khan who finished with a 71 for three under.

"What a moment - it was unbelievable. It was the perfect yardage for my six-iron and it landed about four feet short, took a couple of bounces and went in."
