Big comebacks represent sustained great performance under pressure and make for memorable golf tournaments. In the past, comebacks have typically been at the beginning of the final round (e.g., the winner came from five strokes back at the beginning of the final round). In this talk, a new comeback metric is proposed that considers all times during the event and simultaneously accounts for strokes behind the leader, position on the leaderboard, and the time remaining in the tournament. This metric is used to identify the biggest comebacks in golf. Similar analyses are used to identify the biggest collapses and the grittiest performances in golf.
