Victory also somewhat makes amends as he was second to Irish Open tournament host, Rory McIlroy, in the 2016 event at the K. Club. "It's so hard to win tournaments". Like, just react.' I mean, I pured the putt.
It is the first time Knox has been in the world's top-50 since August 2017 having dropped as low at 137th in May this year.
"To make the Ryder Cup team, you have to win tournaments", Knox said.
Campillo finished the first nine on -6 - with Van Rooyen bogeying on 11th to leave the lead at two strokes. I hit two great putts on 18 and one grazed the edge and one came back at me so I'm happy.
"But I was able to hit a good shot and get on the green, which I was thrilled with".
"All the bad moments are taken care of with putts like that", Knox said.
Fox's consolation was a tee-time into The Open and with Nuneaton's Andy Sullivan (69) and South African Zander Lombard (69) securing the other two Carnoustie places.
Spaniard Jorge Campillo finished one shot out of the playoff after a closing 65, one shot clear of countryman and defending champion Jon Rahm and overnight leader Erik van Rooyen.
In the end, it wasn't to be, after a final round where Fox was in the driver's seat on two occasions. A 30-footer on the eighth and another birdie on the ninth had him in a share of the lead but it would soon be a four-way tie. "My focus is on trying to qualify for the team", added Knox. I've done it before in the US on the last hole, 12 feet.
So Van Rooyen bogeyed again. It was his second tour title.
The 33-year-old found himself with nearly the same length putt from the same location on the first playoff hole. Brandt Snedeker and Jason Kokrak tied for third at 13 under.
The consoloation for Fox is that he did claim one of the Open qualifying spots given to three players in the top 10 and not already exempt.
"There have been a lot of heartbreaks", he said. I'm not putting any pressure on myself. I read the putt and I was like, just don't aim. "Some of these pins you couldn't get to". I read the putt and I was like, just don't aim.
Reigning champion, Jon Rahm, despite carding a 7 on his second hole, roared back and nearly reached the magic -13 mark, coming up just one short.
Knox put his second shot in a position nearly identical to the one he found on the 72nd hole and rolled it home again, with Fox missing his own birdie attempt from 12 feet. His huge fist-pump said it all.
