What Is the Playoff Format at Amgen Irish Open 2025?

6 feet off the pin on the par-4 13th hole, Rory McIlroy needed a birdie to become the solo leader in the 2025 Amgen Irish Open. His putt rolled 360° around the cup before sinking in as if it were a hoop. No one could believe what had just happened, not even the Irishman. Nonetheless, he was now at the top of the table with a 1 stroke lead against the field and 5 holes to play. However, three players still chase him at 14-under, and they might force a playoff. If that does happen, what kind of format will the 2025 Amgen Irish Open playoff have?

The playoff for the Irish Open will be played under the DP World Tour rules. That means, after the regulation 72 holes, the first-place ties will battle in a sudden-death contest to determine who is the champion. They will play the 18th hole, with the winner being determined by who scores the lowest after the par-5 hole.
