IRVING, Texas (AP) - Texan Jimmy Walker and first-round leader Steven Bowditch joined Jon Curran at 9 under Friday atop the soggy AT&T Byron Nelson.
Hometown favorite Jordan Spieth surged into contention with a 5-under 64 and is three shots back.
Walker, who won the Texas Open not far from home in San Antonio in March, finished a 66 at the rain-altered TPC Four Seasons with a par at 18 just before played was halted by darkness. There were 33 players on the course after the start was delayed three hours.
Par was 69 because No. 14 was shortened to a 105-yard par 3 after heavy overnight rain made the fairway unplayable.
Bowditch shot 68 with seven birdies and six bogeys. Curran matched the day's low round at 63.
