Four clear with eight to play, Rose then had a double bogey seven and two bogeys that left him battling for the title again and gave Padraig Harrington a chance to keep his money list crown.
But the Irishman could only finish joint fourth, not enough for him to overtake the absent Ernie Els on the Order of Merit, leaving Rose clear to claim the top European accolade whether he wins the tournament or not.
Things hotted up coming down the straight when Graeme McDowell made an albatross two on the long 17th to tie for the lead, while playing partner Kjeldsen then birdied the hole to go ahead on his own at two under.
He then bogeyed the last and McDowell double-bogeyed it and when Rose and Dyson birdied the 17th they were out in front at two under.
But neither could make par and so they went into sudden death on one under.
