The 23-year-old’s win at the Deutsche Bank Championship means he enters the third FedEx Cup play-off event at the top of the points standings.
The Irishman has been grouped with Nick Watney and Tiger Woods, second and third in the standings, and is happy with his current performance levels.
“I’m very pleased with how I’ve played the last few weeks,” he said.
“(I’m) very pleased at how hard I worked on my game leading up to these few weeks because I felt like it was nearly there, and it just needed to stay patient.”
McIlroy and Woods have won three PGA Tour events each so far this year.
Now McIlroy is determined to add to his tally.
“It’s rare to see guys having six and seven-win seasons,” he said.
“Tiger did it for so many years, three is a great number, I’d like to make it four or five, obviously, after the FedEx Cup.”
