AVONDALE, La. — Chris DiMarco got off to a fast start in his first event since losing the Masters in a playoff, shooting a season-best 7-under 65 on Thursday for a share of the first-round lead in the Zurich Classic.

India's Arjun Atwal also opened with a 65, birdieing six of his final nine holes on the TPC of Louisiana, the Pete Dye-designed course in its first year as the tournament site after 16 years at English Turn.

DiMarco, coming off the emotional first-hole loss to Tiger Woods three weeks ago at Augusta National, had an eagle and five birdies in his bogey-free round in swirling wind gusts. Defending champion Vijay Singh, the Houston Open winner Sunday, was two strokes back at 67 along with J.J. Henry, Tom Pernice Jr. and Tim Clark.

FRANKLIN AMERICAN MORTGAGE CHAMPIONSHIP: At Franklin, Tenn., Kris Tschetter shot a 3-under 69 in driving rain that gave way to windy afternoon conditions to top the field in the first round of the Franklin American Mortgage Championship.

Tschetter, an 18-year veteran who won her lone LPGA Tour title in 1992, had a one-stroke lead over Cristie Kerr, Grace Park and Stacy Prammanasudh on the Vanderbilt Legends Club's Ironhorse Course.
