Even after receiving the biggest cheque of his career, hoisting the trophy and receiving a champion's kiss from his wife, Joel Edwards couldn't believe he had won his first USPGA Tour event.

The 39-year-old American shot a final-round 65 to win the $3.4 million Air Canada Championship with a record equalling 19-under-par score of 265.

"It's the neatest, weirdest feeling," said the soft-spoken Texan. "They can't take it away from me. I've been playing for 25 years and dreamed of something like this happening to me."

Edwards's win was worth $612,000 and pushed his total earnings this year to $1,005,843, the first time in his career he has won more than $1 million in a season.

"It's something you think about for a long, long time," Edwards said referring to his first win. "You think about it your whole life."

Fellow American Steve Lowery forgot about his poor finish to the third round and shot a final 66 to finish second on 272, seven strokes adrift.

"It's a tough game when you play all day today to make up for two holes yesterday," said Lowery, who collected $367,200.

On Saturday, Lowery was eight-under-par over the first 16, then had a double-bogey and a triple-bogey on his final two holes.

Finishing in a tie for third at 11-under were 1999 US Amateur champion Matt Kuchar and Fred Funk.

Edwards's seven-stroke win at the 7,069-yard Northview Golf and Country Club was the biggest victory margin in the event's seven-year history. It also tied for the second biggest on tour this year.
