Chapman led by five after 54 holes and was never really threatened Sunday. His closing 1-over 72 was his worst score of the tournament — but it was enough to give the Englishman a win at the major championship.
Chapman, who had never won on the Champions Tour, finished at 13 under. He bogeyed three of the last five holes but had enough of a cushion that it didn't matter.
John Cook was at 11 under after a 69. Hale Irwin shot 68 to finish another stroke back.
Lone Oak's Kenny Perry shot a tournament-record 62 at Harbor Shores but finished five shots behind in ninth place. Paducah's Russ Cochran shot a final round 65 and finished tied for 29th at 1 under.
