Red Bull reacted, double stacking Max Verstappen and Ricciardo drivers, while Bottas and Vettel weren't able to given they had just passed the pit entrance. The situation worked, and by the time the safety auto period ended, both drivers found themselves up close with the leaders along with fresh rubber.
Vettel, who won the first two races of the season for Ferrari, saw his lead over Hamilton slashed from 17 points to nine.
The Chinese Grand Prix looked like it was going to be a replay of the first two Grands Prix of the 2018 season as Sebastian Vettel took the lead from pole, Bottas put his Mercedes in front of Raikkonen and Verstappen on the ball passing both Hamilton and then Raikkonen to sit in third.
How did Ricciardo do it?Valtteri Bottas (Mercedes) +8,8943. His opportunity came when Pierre Gasly drove his Toro Rosso into team-mate Brendon Hartley.
However, when a mid-race Safety Car was deployed, Ricciardo dived back into the pits to fit a new set of soft tyres, returned to the track and began picking his way through the field, taking the lead from Valtteri Bottas on lap 45 and never looking back.
The Australian, who started sixth on the ultra-soft tyre but very almost missed qualifying after a turbo failure in FP3, made up a place before stopping for fresh medium tyres.
Hamilton and Vettel, who were expected to be fighting it out for the world championship this term, were left in Ricciardo's wake. He launched one of his trademark attacks from way back, to dive down the inside of Hamilton at the hairpin. "They're all pretty fun", added the 28-year-old, who took on fresh tyres under a safety vehicle yesterday. Bottas and Vettel had already passed the pit entry when the safety auto was deployed so could not have pitted. That's why I sent Chris Gent - the No. 1 mechanic on Daniel's auto - up (to the podium) today because those guys have earned us that result.
Due to the incident between Vettel and Verstappen, Renault F1's Nico Hulkenberg was sixth, 21.052 seconds behind race victor Ricciardo with McLaren-Renault's Fernando Alonso a surprise seventh place after Vettel's Ferrari looked vulnerable following Verstappen's collision. He apologised to Vettel afterwards. On the catwalk the company pilot "Red bull" was two Finn, Bottas and Raikkonen.
Lewis Hamilton also endured a frustrating afternoon, finishing in fourth place.
Nico Hulkenberg of Renault was sixth followed by Fernando Alonso of McLaren.
Driver of the dayNo contest this - Ricciardo was stunning in the closing laps.
"I really feel like, just give me a chance to be in a title hunt and I really believe I'll take it".
One Flew Over the Cuckoo's Nest director Milos Forman dies
Forman had more awards success with his 1984 period drama Amadeus , starring Tom Hulce as composer Wolfgang Amadeus Mozart. He left his second wife, singer Vera Kresadlova, behind with the couple's twin sons when he left Czechoslovakia.
Before the start of the 15th edition of the Chinese Grand Prix, you could be forgiven for thinking the Red Bulls weren't in Shanghai for a win, let alone a podium finish.
The result of the Chinese Grand Prix may have been as much about Ferrari and Mercedes mistakes as it was about Ricciardo's great driving, but it made for a cracking race. He managed his tyres well in the opening stint, stayed patient amidst the chaos of the Safety Car period and executed his overtakes perfectly in the second half of the race.
"Fat lip and all I got the win". It was insane, a lot of fun.
"Given where we were 24 hours ago, thanks to the boys", he said from the podium.
"I don't know. I'm sitting here, reciting everything in my head what just happened".
"We have been underperforming". I have got to rectify that and get back into normal performance mode otherwise more points will be lost. "I'm thankful for a couple of incidents that kept us kind of in the battle".
While Ricciardo enhanced his reputation as one of F1's best overtakers, his team-mate Verstappen enhanced his reputation for impetuosity. "This was not what I expected". I had no intention of resisting, there was no point in doing so they were too fast. His race had ultimately been compromised by strategy.
Bottas called it a "fair" pass and finished second with Ferrari's Kimi Raikkonen in third. We stayed out very long and got a little luck on the safety vehicle.
"Now we can all go and celebrate tonight".
"I've only got six - it's not a whole lot but the wins always seem to come under some circumstances".
"I don't think I have to say anything here", a disgusted Vettel said over his radio in an obvious reference to the Dutchman's aggressive style. We were in trouble then really and it is disappointing.
"Saturday and Sunday felt like a disaster from my side", the Briton said, despite setting a record of 28 successive scoring finishes.
