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.
Jordan Spieth was eight shots back in his hometown event, which returned to Dallas after 35 years at the TPC Four Seasons in suburban Irving. Defending champion Billy Horschel shot 68.
Leishman opened with an eagle, started the back nine with three straight birdies and reached 9 under with another eagle at the 14th.
