The tournament uses the Modified Stableford scoring system, which adds and subtracts points rather than relying on the total number of shots taken.
With birdies being worth two points apiece, Romero accumulated 14 points.
He racked up birdies on the second through fifth holes and made the turn with 10 points. He added to his total with birdies on the par-5 13th and 18th holes, but then shot par the rest of the way, for zero points.
The Stableford system awards five points for eagles but subtracts one point for a bogey and three points for a double bogey.
