Mahan (66) tied for Nelson lead

IRVING -- Colleyville's Hunter Mahan completed his first round of the HP Byron Nelson Championship just after 8 a.m. Friday and was tied for the lead after posting a 4-under 66.

Mahan was actually in the lead by himself before missing a 5-foot par putt at No. 18.

Mahan was one of 66 players finishing the first round early Friday. The second round tee times are delayed by one hour.

Mahan has traditionally performed well in this event close to his home. In six previous Nelson appearances, he's missed the cut twice and hasn't finished better than a tie for 42nd.

"I played aggressive because I haven't played well here, so there's no sense in holding back," Mahan said. "I found a rhythm out there."

Mahan was scheduled to get about a 40-minute break before teeing up for his second round. The conditions have favored those that went out late Thursday, despite having to wait around for the delay. The winds, which were blowing on Thursday morning, died down in the afternoon and the conditions are calm this morning.
