1968 Masters champion Bob Goalby has died at the age of 92.
Goalby, who won 11 PGA Tour events, passed away in his hometown of Belleville, Illinois.
The father-of-three famously won the Masters after Roberto De Vicenzo signed for the wrong score and was an early advocate of the PGA Tour.
He was also victorious on two PGA Tour Champions.
Born in 1929, Goalby was a multi-sport player through high school and college, going to to Illinois on a football scholarship, before then playing baseball at Southern Illinois.
He turned pro in 1952 after serving in the Korean War, with his first win coming at the 1958 Greater Greensboro Open.
His win at the Masters a decade later was one of the most extraordinary in the tournament's history, with Goalby winning due to a rules infraction.
He hit 3-iron to 8 feet for eagle on the par-5 15th and closed with a 66 and finished at 11-under 277, leading to him assume that he would go into a Monday play-off against De Vicenzo.
The Argentine had birdied the par-4 17th and finished with a 65, but his scorer Tommy Aaron put him down for a 4 on the 17th hole instead of a 3.
De Vicenzo signed the card, and under the Rules of Golf, had to accept the higher score. That gave De Vicenzo a 66 and he finished one shot behind.
The manner of the win led to Goalby feeling that his performance at that year's tournament had been overlooked.
"The presentation ceremony wasn’t what it could have been," he told Golf Digest.
"I sat next to Roberto and did what I could to console him. There’s video of me patting him on the leg. I felt no elation, nothing like you’d expect from winning the biggest tournament of your life. It was awkward. It was tragic for Roberto, but it was equally unfortunate for me.
“I never did get full credit for what I’d done. I played damned well, especially the last day.”
The last of his 11 PGA Tour titles came in 1971 at the Bahamas National Open, while he also played in one Ryder Cup, in 1963 at East Lake in Atlanta, with Arnold Palmer as the American captain.
Goalby and De Vicenzo remained friends despite the way the Masters ended, and were partners twice in a PGA Tour Champions event.
He also played a key role in developing the next generation, with his nephew Jay Haas winning 27 PGA Tour-sanctioned titles – nine on the PGA Tour, and 18 on PGA Tour Champions.
And Haas has admitted that the passing of his uncle will leave a sizeable hole in the family.
"It’s hard to imagine him not around. He’s been in my life since I can remember. He started me in the game. I haven’t seen him as much in the last 20 years, but we talked all the time, he’d check in with me, and I would check in with him," he said.
"I knew it was coming, but it’s never easy when that time does come. Thoughts for his wife and his three boys, and the people that were close to him. He had a ton of friends, and we will all miss him, dearly miss his stories.
"They kind of broke the mould with him, for sure. I thought about not playing today, but he'd have been p***** if I didn’t play. Tried to do my best, thought of him all day long, and will going forward too.
"He’s not in any pain anymore, so it’s good, but hearing his voice and hearing what he has to say is always pretty special."
