He pitted on lap 31 but continued to struggle for pace, eventually finishing 36 seconds behind race victor - and team-mate - Valtteri Bottas.
Vettel was chasing Valtteri Bottas in the closing stages as the pair went through traffic, and he lost crucial momentum behind Massa. Red Bull is a distant third with 57 points. Big congratulations to Valtteri.
It was the first victory for a Finnish driver in Formula One since Raikkonen won the 2013 Australian Grand Prix and means Bottas is the fifth Finn to win a race in the sport's history.
"Took quite a while, more than 80 races", said Bottas, who had his debut with Williams in 2013.
"The odd opportunity to join this team came in the winter and they made it possible so thanks to them". "We're out of the race now", Hamilton told his team on lap 16.
Hamilton slipped to 13 points behind Vettel in the championship, with Bottas now only 10 adrift of the British three-time champion. The British driver never came close to third-placed Raikkonen, and the gap stood at more than 25 seconds at the checkered flag. His win shows it's not clear-cut who's better suited to take the fight to Ferrari.

"I'm just keen to prove more in the next few races", Bottas said, on Sunday, as quoted by Formula One official website.
Red Bull Racing's Max Verstappen finished fifth a full minute behind the victor, though sadly for his teammate Daniel Ricciardo some brake trouble meant retirement early on.
In other F1 news, it's been confirmed that Sauber will switch from Ferrari to Honda for supply of its power units starting from the 2018 season.
Vettel now has 86 points after the opening four races with triple champion Hamilton, a victor in China, second on 73 and Bottas third with 63.
Bottas held on to the lead in a dramatic end to the race. Verstappen's Red Bull teammate Daniel Ricciardo, a common sight in the top five, retired early after his cars brakes caught fire. However, one lap later with the start of the race, Lance Stroll was clipped by Nico Hulkenberg, but continued in the race, while Romain Grosjean and Jolyon Palmer were involved in a collision, which brought out the safety vehicle for the next three laps.
Bottas went for the pit-stop on Lap 28 giving the lead to Vettel, who lingered on the track a while longer going for his pit-stop about ten laps later.
