It may be quite some time before golf fans are able to witness what took place during Sunday’s final round of the PGA Championship.

At 50-years-old, just weeks before turning 51, Phil Mickelson set a record as the oldest men’s major champion with his sixth major victory. The previous mark, set by a 48-year-old Julius Boros at the 1968 PGA Championship, stood untouched for 53 years.

That caught the attention of 15-time major champion Tiger Woods, who took to Twitter shortly after Mickelson’s win at Kiawah Island Golf Resort’s Ocean Course in South Carolina to congratulate his longtime competitor on the PGA Tour.

Woods has been recovering at his home in Florida since March following a scary accident in Los Angeles in February. It didn’t take long for Lefty to respond.
