The 36-year-old has a 767-point lead at the top of the season-long rankings as he goes for his fourth consecutive Race to Dubai crown.
Hatton and compatriot Marco Penge are the only two who can stop McIlroy from winning the season-long title.
Hatton needs to win the tournament and have McIlroy finish worse than tied for eighth to win it.
“I’m in a better position than him [Hatton],” added McIlroy. “I’m focused on myself. If I go out and play the golf that I know that I’m capable of, especially around this golf course, I know that I’ll be OK.
“It would be an amazing way to end the season.”
Penge shot an improved 68 in round three after scores of 74 and 70, but looks out of contention on four under.
