Cameron Beckman arrived at the Byron Nelson Championship yesterday in jeopardy of missing the cut. He left in first place.
Beckman tied the TPC Four Seasons course record - and set a personal best - with a 61 in the second round in the PGA Tour event in Irving, Texas.
He's at 10-under 130, tied for the lead with rookie Blake Adams. First round co-leader Jason Day is alone at 131.
Adams, a 34-year-old rookie who spent the last 3 years on the Nationwide Tour, was part of a cluster at the top after the first round, piled up six birdies on his way to a 64.
The rest of the leaderboard includes 16-year-old Jordan Spieth, a local high school junior who became the sixth-youngest player ever to make the cut at a PGA event. He's at 3-under.
Spieth is the reigning U.S. Junior Amateur Champion and just last weekend won a state high school title.
"I feel like I played better than my score showed today," said Spieth, who already has accepted a sponsor's invitation to play the PGA event in Memphis, June 10-13.
Steve Elkington, 47, who got in when someone else withdrew Sunday, has shot consecutive 66s and is two strokes off the lead.
