Ken Duke’s 65 at the 2016 Players Championship isn’t close to one of the lowest rounds in PGA Tour history. It’s not even the best round ever at the Players. So why does it qualify as the greatest round in Players history, as well as one of the greatest rounds in the history of golf? In this episode of Local Knowledge, Alex Myers tells the story of a journeyman pro’s improbable round on a difficult scoring day at the Players, along with the backstory of how our measurement of golf performance has grown more sophisticated in recent years. In talking to Columbia University professor Mark Broadie, the creator of golf’s strokes-gained statistic, Myers explores how advanced metrics have altered our understanding of golf, and has helped everyone from tour pros to average players understand where they excel and where they most need improvement.
