Tiger Woods congratulated "truly inspirational" Phil Mickelson after the American made history at the US PGA Championship on Sunday.
Mickelson defied form and age to capture the PGA Championship in history-making fashion following his two-shot triumph over Louis Oosthuizen and Brooks Koepka.
Not since February 2019 had Mickelson won on the PGA Tour, while the 50-year-old's last major triumph came at the Open Championship in 2013.
But Mickelson became the oldest major champion in golf history in South Carolina, where he secured a sixth major title and 45th Tour trophy.
Truly inspirational to see @PhilMickelson do it again at 50 years of age. Congrats!!!!!!!— Tiger Woods (@TigerWoods) May 23, 2021
Watching from the sidelines as he continues to recover from February's single-car crash, 15-time major winner and famous foe Woods used social media to hail Mickelson.
Woods wrote via Twitter: "Truly inspirational to see @PhilMickelson do it again at 50 years of age. Congrats !!!!!!!."
After reigning supreme, Mickelson – who has enjoyed a great rivalry with Woods – said: "This is just an incredible feeling because I just believed that it was possible but yet everything was saying it wasn't.
"I hope that others find that inspiration. It might take a little extra work, a little bit harder effort, but gosh, is it worth it in the end."
