Roberts fires 64 for one-shot lead

Loren Roberts may have failed to qualify for the US Open, but he is the improbable leader after 54 holes of the Buick Classic.

Roberts, who turns 49 next month, fired the best round of the day with a seven-under-par 64, totalling eight birdies and one bogey. He played the back nine in five-under 30, closing with back-to-back birdies to move to 12-under 201.
