As Justin Thomas works to end his three-year drought of winning a PGA Tour event this weekend at the RBC Heritage at Harbour Town Golf Links, he's going the extra mile to make sure he does so with integrity.

Thomas at least ended the day on a high note, rolling in a 15-foot birdie putt on the 18th to make up ground on Si Woo Kim, who played bogey-free until the final hole at Harbour Town. By then, Kim had done enough to still post a 5-under 66 and take a one-shot lead over Thomas (69) and Andrew Novak (66).

A bad break contributed to Justin Thomas briefly losing the lead during the third round of the RBC Heritage on Saturday.
