L'indépendance Luxembourgeoise - McIlroy grabs early lead at Arnold Palmer Invitational

The Northern Ireland star, who won the event in Orlando in 2018 and has top-10 finishes in his last five appearances, had a two-shot lead with afternoon starters still on the course.

"I feel there's a nice flow to this golf course where you can really build a score," McIlroy said.

"You have par-fives, one every few holes, and you've got a couple of scorable par-fours. As long as you don't do anything stupid and you keep it in play, you feel like you can sort of methodically build a score on this golf course.

"I played the par-fives particularly well, and that was the bulk of the score," added McIlroy, who had three birdies and a 41-foot eagle putt to play the four par-fives in five-under.

McIlroy teed off on 10 and missed an eight-foot birdie chance at his opening hole. He was unable to get up and down from off the green and made bogey at 11.

But he followed a two-putt birdie at the par-five 12th by a birdie from the fringe at 13.

He rolled in his 41-foot eagle putt at 16 then birdied 18 to make the turn four-under.

Back-to-back birdies at the third and fourth saw him grab the solo lead and he made his last birdie of the day at the par-five sixth.

McIlroy said iron play was the key to his success on the par-fives.

"I hit a four-iron into 12 and a four-iron into 6. They were probably two of the best long irons I hit in a while. So when I start hitting long irons like that, I know my swing's in a pretty good place. Seeing shots like that certainly gives me some confidence."

Three players -- Beau Hossler, J.J. Spaun and former FedEx Cup champion Billy Horschel -- were in the clubhouse on five-under 67.

Spaun had five birdies without a bogey, Hossler bagged six birdies and Horschel had five birdies and an eagle at 16 -- where he landed his second shot 10 feet from the pin.
