Jordan Spieth among HP Nelson leaders

IRVING, Texas -- Dallas high school senior Jordan Spieth is proving success a year ago at the PGA Tour's HP Byron Nelson Championship was no fluke.

The 17-year-old Spieth shot a 2-under 68 Friday and is in a six-way tie for eighth at 3-under through Friday's second round, five strokes behind Ryan Palmer.

"I want to win," Spieth said. "I don't care what everyone else says, I look at the leaderboard and I see 8-under. Ryan Palmer posted a ridiculous round again today. I'm confident, staying loose and seeing my friends in the crowd and feeding off the crowd helps me."

"I'm happy with the way it went," Spieth said. "I'm five shots back, so I have some work to do in the next couple of days."

The afternoon wave, which includes Dustin Johnson and Sergio Garcia, had yet to tee off as high winds were making scoring conditions difficult on the par-70 TPC Las Colinas layout.

Spieth electrified the Nelson crowd last year by becoming the sixth-youngest to make the cut in a PGA Tour event. He entered the final round tied for seventh and stayed in contention until the final nine holes, finishing tied for 16th.

The Dallas Jesuit Prep senior, cheered on by a large gallery, made five birdies (all on par 4s) and three bogeys -- including on his final hole to drop out of a fourth-place tie.

"The crowds got bigger and bigger and that was awesome," Spieth said.

Spieth's success will make his weekend even more hectic. As it stands, his participation in Jesuit's graduation ceremonies late Saturday afternoon is in jeopardy.

"Right after the round, I'm going to shoot over there as quickly as possible," Spieth said. "My name starts with 'S', so it will be toward the end. We'll see."

Spieth, however, made it clear that if it came down to one or the other, he'll choose playing in the third round over the cap and gown ceremonies.
