Three-time Masters champion Phil Mickelson gave himself a sniff of another green jacket success as he rolled back the years at Augusta.
The American won in 2004, 2006 and 2010 and swept up the leaderboard into second place on Sunday thanks to a 65, setting an eight-under-par clubhouse target.
Jon Rahm was out on the course on 11 under through 13 holes, having overtaken Brooks Koepka on the front nine, so Mickelson needed the Spaniard to suffer a late collapse to have a chance of the title.
Mickelson and Koepka have been among the star names who have defected to the LIV Golf series in recent times, while Rahm was flying the flag for the PGA Tour, as players from both circuits went head to head for major glory.
Speaking after his stellar closing round, Mickelson said: "This is as much fun as I could possibly have playing golf.
"The final round of the Masters, and to play the way I did and finish it off with two birdies – this has been a lot of fun. Regardless of the outcome, this has been a really fun day for me."
Mickelson and the LIV Golf set have pocketed fortunes for joining that Saudi-backed series, but they relish the big occasions such as the Masters.
"I'm grateful we get to be here, to play and compete and be a part of this great championship, and to play like I did today was extra special," Mickelson said.
The 52-year-old was thrilled to shoot as low as he did, and he told Sky Sports it was his aim "to shoot low scores and continue playing at a high level".
"I have a unique opportunity given I'm physically not having any issues, and I'm able to play and compete and swing the club the way I want to," Mickelson added.
"If I can focus and work on my game, I can take advantage of this unique opportunity I have and try to do some special things in the game."
Speaking for the LIV players, Mickelson added: "We're all really appreciative to be a part of this. I think it's great for the championship to have all the best players in the world here, playing and competing.
"It's fun for me as a past champion to be able to be a part of this and continue to be a part of this great championship."
