Questions remain over whether Ricciardo will ever be seen behind the wheel again, with retirement now a realistic option for the popular racer.
The eight-time race winner had struggled to find any consistency since joining RB in 2023, and his results over recent months have now prompted the team to make a change for the final six races of the year.
His achievement also provided a helping hand to his former Red Bull team-mate Max Verstappen, who is embroiled in a fierce battle with Lando Norris for the drivers' title.
The McLaren driver had looked in prime position to add the fastest-lap bonus point to his race-winning tally until Ricciardo's late heroics, prompting Verstappen to relay a message of thanks over team radio.
And speaking after Sunday's race, Ricciardo revealed he had extra motivation to make the last-gasp switch to soft tyres in order get the job done.
“I heard something about $3.5 million bonus for fastest lap," he told Autosport. "Red Bull was throwing some crazy number around!"
“I had an idea, but I also thought they were just letting me have some fun because we were obviously a long way out of the points.
“So then yeah, at the end, the fastest lap. I'm kind of hoping Max wins by a point now, because I guaranteed myself a very nice Christmas present if so. So sorry Lando! But I think I'd get a good Christmas present!"
