Dubai World Championship leaderboard: Keep up to date with the scores on day four

The European Tour reaches what promises to be a thrilling climax this week at the Dubai World Championship.

Rory McIroy can win the Race to Dubai – but only if he is victorious come Sunday and current leader and world No 1 Luke Donald fails to finish in the top nine.

Robert Karlsson took the title last year, beating Ian Poulter in a play-off at the Earth Course, and you can keep track of all the latest scores right here.
