DALLAS -- Marc Leishman followed the best round of his PGA Tour career with a 5-under 66 at the AT&T Byron Nelson on Friday, breaking the 36-hole tournament record previously shared by Tiger Woods.
The Australian was at 15-under 127 for a one-stroke lead over Aaron Wise, the 21-year-old rookie who shot a bogey-free 63 at the new links-style Trinity Forest course.
Hometown star Jordan Spieth matched Leishman's 66 to remain eight shots back.
Leishman opened with a 61 in Trinity Forest's debut after the Nelson spent 35 years at the TPC Four Seasons.
