Scott Stallings has marched to a significant lead at the True South Classic in Madison, Mississippi, with only darkness able to put a halt to his slashing run on day three (Saturday, local time).
Having posted an excellent eight-under 64 in the second round Stallings made further progress with four birdies and eagle in the space of just six holes between the third and the eighth.
The 27-year-old made par at the tenth hole before bad light forced players off the course. He sits at 18 under the card overall - four strokes ahead of fellow Americans Heath Slocum, Billy Horschel and Jason Bohn.
Slocum is also on a hot streak, charging to six under for the day through 13 holes to provide a potential threat to Stallings’ stranglehold over the lead.
Horschel and Bohn were both one under after nine holes when they too had to abandon their rounds.
William McGirt is in the clubhouse at 13 under following an eight-under 64, while Woody Austin, Tommy Gainey and Patrick Reed all compiled rounds of 66 to be equal sixth at 12 under the card.
The best-placed Australian is Steven Bowditch in a share of 14th position at 11 under. Bowditch is even for the day after ten holes.
