American Rickie Fowler has opened up a one-shot lead at the top of the leaderboard after the first round of the Houston Open.
Fowler, 28, registered eight birdies in a bogey-free 64 to sit one shot ahead of Sung Kang, while Stewart Cink is among three players to share third position after the opening round.
England's Justin Rose hit a five-under 67 in the opening round, while Luke Donald registered a one-under 71 ahead of the second day of the event in Houston.
Fowler made a flying start to the tournament after hitting five birdies in his first seven holes, racing to five-under as he warmed up for next week's Masters in style.
Open champion Henrik Stenson, however, is facing the cut after struggling to a 74 in the opening round.
