Scott Piercy has a two-shot lead after day one of the Shell Houston Open following an opening round of 63.
The American started on the front foot, birdieing the opening four holes before picking up another stroke at the sixth.
Piercy then sunk a 31-foot putt for a two at the ninth, to reach the turn in six-under-par for his round.
The 36-year-old continued his faultless round with further birdies at 10, 13 and 18 to reach nine-under and lead by two from JB Holmes.
Holmes held an eagle putt at the 10th, picked up six more birdies and one bogey on his way to seven-under-par.
