John Pak said there was "a fire lit under me" after the Knicks' loss to the Pacers, and the PGA Tour rookie shot a 7-under 63 to lead the Charles Schwab Challenge.

Instead, it's a new face atop the standings after Thursday. American John Pak is 7-under par after one round, three strokes ahead of the field. While this isn't an insurmountable lead by any means, it is a phenomenal showing for someone with only one top-25 finish in his career.

Davis Riley returns as the defending champion, having shot a final-round 70 to finish at 14 under par and claim his first individual PGA Tour title at last year's event.
