Driving on extremely worn tyres at the end of the race, Vettel did enough to stay ahead of Bottas who attacked the German on the last two laps of the 57-lap race around the 15-turn, 5.412km Bahrain International Circuit.
Bottas could not explain why Mercedes looked off the pace in Bahrain after looking dominant in the season-opening race in Melbourne.
"I'm ok", the Dutch driver told his team, after an initial outburst that was not appropriate for a family audience. "I don't know what we are going to be able to achieve tomorrow, but I hope I can do something". Really happy that I got the second run and got it clean.
Raikkonen topped the leaderboard just ahead of Ferrari teammate Sebastian Vettel by 0.011 seconds.

Despite putting in more laps (38) than anyone in the 20-strong field at the 5.4km desert circuit, Toro Rosso driver Hartley couldn't eke anything extra out of a auto which is on the verge of an upgrade. With further stops required, Ferrari's problems were compounded after 36 laps when Raikkonen came in and inadvertently ran over a mechanic as he pulled away. The Finn hit the gas before the left-rear had been changed and struck a mechanic's leg. Raikkonen stopped in the pitlane with three new tyres and the unchanged old one on his vehicle and retired. Hamilton is still on course to rack up his 27th successive points finish, a result that would equal Raikkonen's all-time record. "I started ninth so third is not that bad".
But it was not all good news for Ferrari as Vettel's team-mate Finn Kimi Raikkonen failed to finish after colliding with a mechanic at a pit stop. "He drove into my left rear and gave me a puncture and also destroyed the diff".
