This was McIlroy's first competitive appearance since bowing out of the FedEx Cup race after finishing 59th at the BMW Championship on September 7th.
“I felt I was a little rusty after the four weeks off,” the 24-year-old Northern Irishman said, “but I battled back nicely and to end up under par for the day wasn’t too bad.”
Jang Ik-jae leads the tournament at 4-under. McIlroy, currently ranked sixth in the World Rankings, is three shots back in 12th place. He tied for third at the Korean Open in '09 and was the runner-up in '11.
