F-15: Players who qualified for the 2025 season-ending Charles Schwab Cup Championship

Tim O'Neal will make his U.S. Senior Open debut after advancing to the 2025 Charles Schwab Cup Championship last fall. O'Neal earned a spot in the 2025 championship at The Broadmoor, but withdrew due to an arm injury. O'Neal owns one victory since joining PGA Tour Champions, the 2024 Dominion Energy Charity Classis. He also claimed three victories on the PGA Tour Latinoamerica. He has claimed victories on four continents: North America, South America, Africa and Europe. He's also endured heartbreak at PGA Tour Q-School, twice failing to earn his card by a single stroke. While at Jackson State University in Mississippi, O'Neal amassed 16 victories. He also won the 1997 Georgia State Amateur. For a brief time during his professional career, actor Will Smith sponsored O'Neal. His first sanctioned PGA Tour event came at the age of 42 when he qualified for the 2015 U.S. Open at Chambers Bay.
