In October 1992, O'Connor was nominated by his club for the captaincy of the Kilkenny senior team. He later claimed a third successive Leinster Championship medal on 18 July 1993 after captaining the team from right corner-back to a 2-12 to 0-11 defeat of Wexford in the final replay. On 5 September 1993, O'Connor captained Kilkenny to a third successive All-Ireland final appearance with Galway providing the opposition. He ended the game with a second All-Ireland winners' medal after the 2-17 to 1-15 victory. In accepting the Liam MacCarthy Cup, O'Connor caused something of a minor controversy when he used his speech to suggest that it was time for the GAA to formally fund a holiday for the All-Ireland finalists. He ended the year by winning his only All-Star Award.
