Vijay Singh won the SAS Championship on Sunday at 63 years old, firing a final-round 69 to beat the field by two shots. The Fijian claimed his second PGA Tour Champions victory of the season and became only the second player ever to win on the circuit at that age. Singh has thrived since joining the 50-plus tour, proving age is irrelevant when you still have the game. The win keeps him competitive in the SAS Tour Champions standings heading into the final stretch of the season. For a player who dominated the PGA Tour for two decades, this late-career resurgence on the seniors circuit shows Singh remains one of the tour's most dangerous competitors.
