He finished at 23-under-par 193, which ties for second all-time on the Champions Tour for lowest score in a 54-hole event. The 23 under par is the lowest score in relation to par in a 54-hole tournament in Champions Tour history.
Funk birdied the final hole and Tom Kite bogeyed it, making the margin of victory 11. That bested the previous Champions Tour record for largest margin of victory by two.
All in all, not a bad week.
'Really, the first two days I didn't hit the ball all that great. I putted great all three days,' said Funk, who pocketed $240,000 for the victory. 'It was a love affair with the golf course.'
The win was Funk's second on the Champions Tour after capturing last year's AT&T Championship. Funk, 50, intends to play almost exclusively on the PGA TOUR this season as he is exempt thanks to winning the Players Championship in 2005.
'No, my schedule is the same right now, but it feels good to turn a corner,' he said.
Kite threw away an easy runner-up finish down the stretch. He dropped three shots in the final two holes to shoot a 1-under 71 and fall into a tie for second at 12-under-par 204.
Loren Roberts, the 2006 Turtle Bay champion, posted a 6-under 66 to join Kite, Tom Purtzer (66), Denis Watson (68) and sponsors invite Kiyoshi Murota (72) in joint second.
Funk began the final round with a three-shot lead and wasted little time in extending the margin. He kicked in a short birdie putt at two, then tapped in another short birdie putt at the third. Funk birdied the fifth and the rout was on.
Funk birdied the seventh hole, then played a 6-iron 9 feet short of the target at eight. He sank that birdie putt and made it three in a row with a 6-footer at the ninth.
Kite closed the gap some, but Funk fended off a two-shot swing with a 7-foot par save at the 13th. The momentum of the par saved showed as he drained a 15-foot birdie putt at the next hole.
Funk gave himself routine looks at birdie, but missed the next three holes. At the par-5 finishing hole, Funk knocked his ball over the green with his second and got up and down for the record-setting birdie.
'Last week I was really struggling and Sony I really struggled,' acknowledged Funk, a seven-time winner on the PGA TOUR. 'It started to come around with the putting and my ball-striking came back around today.'
Tim Simpson (68), D.A. Weibring (68) and David Eger (69) shared eighth place at 11-under-par 205.
Scott Simpson (67), David Edwards (65) and Mike Reid (69) tied for 10th at minus-10.
