Matt Wallace and Camilo Villegas share the one-stroke lead after the opening round of The RSM Classic.

Wallace and Villegas, who both played the Seaside Course at Sea Island Golf Club, carded six-under-par 64s on Thursday.

Colombian golfer Villegas birdied his last hole to end the round bogey-free and claim a share of the lead with England’s Wallace.

Villegas – making his seventh RSM Classic start – is seeking his fifth PGA Tour victory and first since the 2014 Wyndham Championship.

Wallace, a four-time winner on the European Tour still eyeing his maiden PGA Tour crown, holed eight birdies and two bogeys to top the leaderboard. 

Rory Sabbatini, Peter Malnati, Cameron Tringale, Adam Long, Patton Kizzire, 2014 winner Robert Streb, Keegan Bradley and Doug Ghim are five under heading into the second round.

Zach Johnson opened with a 66 in his 11th RSM Classic start, marking the third occasion to start the event with a sub-70 score. He claimed top-10 finishes in 2017 (tied for eighth) and 2018 (tied for seventh). 

Former U.S. Open champion Justin Rose posted a two-under-par 70, while Australian star Jason Day shot a 69. 

Defending champion Tyler Duncan – playing the Plantation Course – struggled to a four-over-par 76.
