Jimmy Walker currently leads the way
Rory McIlroy has had a disappointing start to the US PGA Championship golf.
The two-time winner shot a 4-over-par 74 on his opening round in New Jersey.
McIlroy was in a group with defending champion Jason Day, who ended on 3-under and Phil Mickelson, who was 1-over.
Jimmy Walker currently leads the way with a 5-under score after shooting a 65, one ahead of Emiliano Grillo.
