DALLAS — Marc Leishman shot a 10-under 61 on the new links-style Trinity Forest course to take the first-round lead Thursday in the AT&T Byron Nelson.
Leishman opened with an eagle, started the back nine with three straight birdies and reached 9 under with another eagle at the 14th.
The 34-year-old Australian, a three-time PGA Tour winner, had chances to go lower but settled for a 10-foot birdie putt at the par-3 17th for the lowest round of his PGA Tour career. He was a stroke shy of the Nelson record.
J.J. Spaun and Texan Jimmy Walker shot 64. Spaun had six birdies in a span of seven holes for a 30 on his second nine — the front nine on the undulating layout with no trees or water hazards a few miles south of downtown Dallas.
