The Australian took down 2009 champion Angel Cabrera on the second playoff hole last year to win his first major championship. Scott birdied the 18th in regulation with Cabrera watching from the fairway.
Cabrera was undaunted, stuffing his approach within three feet and kicking it in for a closing birdie to reach 9-under and force the playoff. Both players got up and down for par on the first extra hole.
On No. 10, the second extra hole, Scott poured in a 12-footer for birdie and the win. It was his ninth win on the PGA Tour.
