Despite repeatedly warning his team that wasn't convinced the tyres would last to the end, he finally brought the vehicle home in third, 17 seconds behind race victor Daniel Ricciardo. The 33-year-old Englishman spent much of his outing grumbling about his tyres, and although he will take some comfort from losing only three championship points to Vettel at one of Mercedes' bogey tracks, he took aim at its dreary spectacle.
"You have done an wonderful job today", team boss Christian Horner said after Ricciardo took the checkered flag 7.3 seconds clear of Vettel for his second win of the season and seventh of his career.
Ricciardo's victory was a becoming manner for Purple Bull to have a good time its 250th race in Method One, throughout which period it has secured 57 victories and 113 podium finishes, to not point out taking pole on 59 events. Yes, Monaco is a tough track on which to pass, but Ricciardo's demeanour when told he'd have to manage his power problems for the rest of the race - calm, analytical, concentrated - was that of a man desperate not to let this win go, and in stark contrast to several of his rivals who moaned about tyres, traffic and strategy when situations called for calmer heads. "It would've been nice to have come second but I did everything I could".
"OK mate, we can see what's going on", his race engineer replied after a pause.
For lap after lap, he kept the gap until Vettel's tyres showed signs of wear. "And if you look at Ferrari, I imagine Kimi will want to continue - he is driving really well this year and doesn't seem to be ageing".
"From two years ago I feel we got some redemption now, we can put 2016 behind us", he added.
Just a few laps into the race, Sirotkin was told to go to the pits for a 10 second stop, and go after his vehicle didn't have all four wheels on at the three-minutes-to-go point as required in the rules.

For Russia, stability is more important than a short-term significant growth in price, he said in the interview. Crude stocks at the Cushing, Oklahoma, delivery hub fell by 1.123 million barrels.
"I don't think we'll be able to maintain that kind of rhythm in a circuit like Montreal", he said.
A largely processional race saw the safety vehicle stay in the pits, with only a virtual safety auto needed in the closing laps.
As it turned out, Ricciardo was racing with a almost 2-second deficit.
