Former champions Justin Leonard and Todd Hamilton have committed to playing in The Open at Royal Troon, potentially increasing the field size for this year's tournament. The eligibility of past winners who make a return to the event allows for some flexibility in the number of participants. Leonard, who last played in the major eight years ago at Royal Troon, and Hamilton, who last appeared in 2018, will help ensure that alternates will not be needed unless the field drops below 156 players. This reflects the established tradition of former champions returning to the site of their triumphs, adding an interesting dynamic to the competition. Despite the consistent field construct of The Open, the possibility of past champions re-entering the fold highlights the unique nature of this prestigious golf event.
