Tiger Woods congratulated Phil Mickelson on his 'truly inspirational' win at the PGA Championship

• Phil Mickelson won the 2021 PGA Championship, the sixth major victory of his career.
• Nearly 51 years old, Mickelson is the oldest player to win a major in the history of golf.
• After the win, Tiger Woods congratulated Mickelson for his "truly inspirational" performance.

Phil Mickelson is once again a major champion.

Mickelson held off charges from Brooks Koepka and Louis Oosthuizen to lift the Wanamaker Trophy at the PGA Championship.

Mickelson played an up-and-down round but settled in and built a two-stroke lead heading into the 72nd hole of the tournament.

With the green mobbed by fans on all sides, Mickelson two-putted his way to victory.

Woods did not play in the 2021 PGA Championship as he is still recovering from the car accident he was in earlier in the year.

While it's unclear when Woods will be fit to play again, Mickelson will have plenty to brag about to his old friend whenever they are paired together next.
