Scottie Scheffler coasted to a score of five-under 66 on Saturday to maintain an eight-shot lead headed into the final day of The CJ Cup Byron Nelson in Texas.
The world number one looks all but certain to claim his first Tour win of the year, as he split seven birdies with two bogeys in the third round to improve to an overall score of 23 under.
Scheffler is trailed by the trio of Erik van Rooyen, Adam Schenk and Ricky Castillo, who are all tied on 15 under par.
Kurt Kitayama and Jhonattan Vegas are a shot further back.
Ireland's Seamus Power missed the cut by two shots on Friday.
