    Official 2005 winner and stroke total, independently matched to PGA TOUR 2026 Media Guide page 40: https://pgatourmedia.pgatourhq.com/static-assets/page/files/mediaguides/2026%20Media%20Guide_03.16.pdf. Playoff status follows the WINNERS column, with the 2005 rain-shortened playoff confirmed by official tournament history. Score relative to par is withheld because the historical PGA overview contains inconsistent values. Unofficial PGA TOUR win; this row records the completed tournament result and must not be counted as an official Tour victory.
