(CNN) -- Australian Marcus Fraser leads going into the final round of the Scandinavian Masters on the monster Barseback course in Sweden.
Greg Norman powered into the lead at the British Senior Open with a 64.
Fraser, bidding for his second victory on the European Tour, carded a three-under-par 70 on the 7,665 yard layout, the longest in Tour history.
But overnight leader Ricardo Gonzalez of Argentina and second-placed Lee Slattery of England both slipped back.
Gonzalez carded a four-over-par 77, while Slattery, one behind at halfway, could do no better than 75.
Fraser is on eight-under 211, one in front of Slattery, Swede Martin Erlandsson and in-form Dane Jeppe Huldahl, who claimed the Wales Open at the start of last month.
Gonzalez is still in contention on six-under, the same mark as England's Marcus Higley who shot a 70.
Fraser, who came home with three birdies on the back nine, said he kept battling on.
"Just keep plodding along - that's all the mindset was," he told the official Tour Web site www.europeantour.com.
"This is a tough course."
In the British Senior Open at Sunningdale, Australian Greg Norman charged to the top of the leaderboard with a superb third round six-under-par 64.
It left him with a one-shot advantage at 10-under 200 from overnight leader Fred Funk, who slipped up with a two-over 72 and his fellow American Loren Roberts (67).
British Open hero Tom Watson is six shots back after a level-par 70, tied for 14th.
