End of dream for McDowell
There is a large sign at the back of the 18th green in Dubai declaring 'The Race Ends Here'.
However, despite his lowest round of the week, Graeme McDowell's Race to Dubai title hopes ended on day three of the season-ending event.
McDowell heads into the last round 10 strokes behind Ian Poulter (69), who leads by two strokes on 12-under par from three players; Italy's Francesco Molinari (68), England's reigning Irish Open champion Ross Fisher (71), along with Thailand's Thongchai Jaidee (69) at 10- under par.
Kaymer's 73, which included a double-bogey on 18, left him in a share of 11th place on six under par but 19 places ahead of McDowell, and with McDowell now needing to finish first or second to deny the German.
"Unless I shoot 55 tomorrow, he's going to win the Race to Dubai," said McDowell, who acknowledged the talent of the reigning US PGA champion. "I've learned a lot about him (Kaymer) in the last couple of months, and he's extremely driven, and just doesn't show much emotion. He's the best and he's been one of the best players in the world this year, and he certainly deserves everything he's achieved."
Rory McIlroy produced the best round on day three, a 66 to move into a share of ninth place on seven-under par.
Peter Lawrie (68) is at five-under par, Padraig Harrington (69) on three-under, Darren Clarke (73) at one-under, Gareth Maybin (77) at five-over and Damien McGrane (77) in last place at 13-over par.
