Phil Mickelson wrapped up his fifth victory at the AT&T Pebble Beach Pro-Am on Monday after play was extended into an additional day.
The 48-year-old five-time major winner finished on 19 under after returning to the California course play the closing two holes of his final round.
Third-round leader Paul Casey finished second on 16 under with Mickelson’s fellow American Scott Stallings a shot further back.
Mickelson, who had also led by three when play was suspended due to bad light on Sunday, finished with a birdie at the last to sign for a closing seven-under 65.
Casey, who had been three ahead after 54 holes, also birdied the last to put some shine on an otherwise frustrating one-under 71.
Mickelson’s win equalled Mark O’Meara’s record number of victories in the tournament and saw him become only the second man after Tiger Woods to surpass 90million US dollars (£70million) in career earnings.
Mickelson, whose victory was also his 44th on the PGA Tour, told reporters: “This is a special place to win at.
“I have so many incredible memories and recollections here over the years and to be able to add to them is something special.
“To play some of my best golf on a Sunday and catch such a good player as Paul Casey means a lot to me.”
Former world number one Jason Day finished in a tie for fourth on 13 under with Kim Si-woo.
