A golf-ball mix-up between Cameron Davis and Will Zalatoris in the final round of The Sentry cost the players financially.
Australian Davis and American Zalatoris played alongside each other during Sunday's final round of the PGA Tour event in Hawaii and unintentionally hit each other's golf ball on the 15th hole.
The players subsequently incurred a two-shot penalty, although would have been disqualified had they not corrected their mistake.
Davis finished joint-13th on 22 under par and took home $410,000 (£328,414) but would have pocketed $715,625 (£573,222) and finished fifth without his error, so missed out on a whopping $305,625 (£244,808).
Zalatoris, meanwhile, took home $163,333 (£130,831) after finishing tied for 26th, when he could have ended 15th and scooped $283,200 (£226,846) so he was denied $119,867 (£96,014).
Japan's Hideki Matsuyama won the tournament with an astonishing 35-under-par total of 257, the PGA Tour's record score across a 72-hole event.
