Abu Dhabi: A clearly frustrated Daniel Ricciardo felt "helpless" as his dreams of a fairy tale podium finish with Red Bull slipped away in the desert night at the Abu Dhabi Grand Prix.
After leading the race for 15 laps the Australian, who will join Renault next season, was forced to pit on lap 34 which saw him return to the track in fifth position on Sunday.
He was able to overtake a faltering Valtteri Bottas but was unable to make up ground on the top three of world champion Lewis Hamilton, Sebastian Vettel and Red Bull teammate Max Verstappen.
"I'm all right, it wasn't the most exciting race," a downbeat Riccardo said afterwards.
"It was fun [leading] but [pitting late] just put me out of reach of the leaders.
"I don't know if we had any other options. Obviously we could have pitted early and kept track position. It's always hard to know [the best strategy].
"I don't think anyone thought [the tyres would last to the end]. Lewis pitted really early and [probably] didn't think he would last so strongly to the end."
Finding himself stuck behind Verstappen with laps running out the 29-year-old said he "felt kind of helpless at the end there".
"I couldn't really do too much. The pace advantage originally was strong but that fell away quite quickly. We probably weren't quick enough.
"I was a bit lonely on the last few laps. I couldn't do much more. Obviously third and fourth was great for the team, it's solid.
"We close this chapter now. Thanks to Red Bull, I would have loved to drink out of my shoe but who knows? There are still a few hours to go yet."
Earlier, Ricciardo's new Renault teammate Nico Hulkenberg crashed out after flipping on the opening lap following contact with Haas' Romain Grosjean
Ricciardo was up to third on the ninth lap following Kimi Raikkonen's exit due to power loss and Hamilton pitting early.
When Vettel and Bottas also chose to pit on lap 17 Ricciardo went into the lead for the 100th time in his 100th and final race with Red Bull.
As the rain and lighting swirled around the Yas Marina circuit the Monaco resident clearly enjoyed his time at the top of the field, running on ultrasoft tyres he built his lead almost to seven seconds.
But his tyres began to degrade on lap 27 reducing his lead over Hamilton to just three seconds.
He finally pitted on lap 34 and changed to supersoft, returning to the track in fifth spot, eight seconds behind Verstappen.
Hamilton's 11th win of the season saw him finish 88 points clear of Vettel in the driver standings with Ricciardo in sixth.
Mercedes also claimed the Constructor's championship ahead of Ferrari with Red Bull in third.
