Sepp Straka is among four players tied for the one-stroke lead following the opening round of the Corales Puntacana Resort and Club Championship.
Straka carded a seven-under-par 65 and he was joined by Scott Harrington, Hudson Swafford and Tyler McCumber atop the leaderboard in Punta Cana in the Dominican Republic on Thursday.
A Web.com Tour champion but eyeing his maiden PGA Tour title, Austria's Straka was flawless on day one following an eagle and five birdies at Corales Golf Club.

Zhang Xinjun and Joseph Bramlett are tied for fifth, while Ricky Barnes, Cameron Percy, Justin Suh, David Hearn, Kyle Stanley, Sean O'Hair, Jamie Lovemark, Brian Stuard, Patrick Rodgers and Ryan Brehm are a shot further back.
