Shunned by many in the golf world after leaving the PGA for the LIV tour, Phil Mickelson asserted himself in the final round of the Masters. He shot a sizzling 65 in the final round of the tournament.

The spectacular round allowed Mickelson to set a record for the lowest round in Masters history by a player 50 or older. Mickelson finished the 72 holes of the Masters with a score of 8 under par. That left him as the leader in the clubhouse.

Jon Rahm had a 2-stroke lead on the field as he played the back nine, but he had 6 holes remaining. The back 9 on Sunday at the Masters is when the title is almost always decided. Rahm could either lengthen his lead or fall back. If Rahm loses 2 strokes to par over his closing holes, he would be left in a playoff position with Mickelson to decide the title.

Mickelson, 52, made his move with a series of brilliant fairway shots and some spectacular putting. Fellow LIV player Patrick Reed was also mounting a surge on the back 9, reaching 7 under par through 15 holes.
