Tyler McCumber, Sepp Straka, Hudson Swafford and Scott Harrington share the lead after day one of the Corales Puntacana Resort and Club Championship on a day of low scoring in the Caribbean where nearly two-thirds of the field broke par.
The quartet find themselves one stroke clear of Xinjun Zhang and Joseph Bramlett, with a host of players a further shot behind including Kyle Stanley and Ricky Barnes.
"This course is not really one where you can push it," said day-one leader Straka. "You can shoot a low round out here, but it’s got to be a consistent low round."
Belgium's Thomas Detry got off to a solid start in his bid for a maiden individual success at 4-under par alongside one of the tournament favourites Mackenzie Hughes and Kelly Kraft - the latter who made a walk-off hole-in-one on the 9th just two holes after having made an eagle-three on the par-5 7th.
