In the dark: Spieth shoots 64, a shot back at Byron Nelson

IRVING, Texas (AP) Jordan Spieth finished off a 6-under 64 just before dark Thursday and was within a stroke of the lead when the first round of the AT&T Byron Nelson was suspended.

Sergio Garcia, Danny Lee and Johnson Wagner all shot 63. Lee and Wagner, like Spieth, were just able to complete the round that started 2 1/2 hours late after early morning rain.

Dallas native Spieth, who just missed a long eagle chance on the par-5 16th that would have matched the lead, is playing only his second tournament since squandering a five-stroke lead on the back nine at the Masters. The world's No. 2-ranked player missed the cut last week at The Players Championship.

Dustin Johnson and Freddie Jacobson also had 64s. Tom Hoge, one of 30 players unable to finish, was 6 under through 14 holes.
