Paul Casey and Peter Hanson separated themselves from the logjam on the leaderboard to lead the Volvo Champions by one stroke after the third round on Saturday.
The leading eight players were separated by only three shots in the new European Tour event.
England's Casey and Sweden's Hanson shrugged off indifferent starts and made a bunch of birdies in the middle portion of the Colin Montgomerie-designed Royal Golf Club course, and then both missed putts from inside five feet on the final hole.
Casey came in with a bogey-free 6-under-par 66, while Hanson dropped just one shot _ on his first hole _ for a 67. That lifted them to 16-under 200 totals and a one-stroke lead over Northern Ireland's Darren Clarke (67) and South African James Kingston (67).
