Clark’s tee shot on the par-4 third hole landed in the fairway, bounced in the air and returned to his own pitch mark.

The course played about two strokes easier for players with later tee times, aiding Wyndham Clark's round that ended with a 5-under 67 and a two-shot lead.

Wyndham Clark is having a strong week at the Arnold Palmer Invitational, but he flirted with disaster on Friday's front nine.
