Billy Mayfair also shot 69 for his best finish since a tie for third at the 2001 British Open. He finished in second place at 12-under-par 268. David Toms, Peter Lonard and Joe Durant were one stroke further back.
Perry, who got his ninth PGA Tour win, was on a streak of 53 consecutive holes without a bogey before he double-bogeyed Sunday's 17th. He parred the last hole to tie the tournament record of 261 that he set in 2003.
"I was hoping to shoot 21-under, but just came up short," said Perry, who earned $1,008,000 Sunday. "It was a great week."
