Jenson Button had no complaints with his P4 in qualifying and in fact was surprised to have beaten Nico Rosberg.
Throughout the practices for the Bahrain weekend it looked as if Rosberg would be the one challenging for pole position come Saturday's qualifying.
But, when it mattered most, the Mercedes driver just didn't have the pace to get to the front.
Rosberg's miss was Button's joy as the McLaren driver, who was only 0.289s off the pace set by Sebastian Vettel, will line-up on the second row in fourth place.
"P4 is not too bad, it's pretty close at the front and unexpectedly we are ahead of Nico - which is a shock," Button told Sky Sports F1.
"We're pretty good at starts so hopefully we'll have another tomorrow."
He added: "You just don't know what is going to happen.
"We knew that the Red Bulls would be quick in qualifying, but we didn't expect to be so far up. So not a bad day at all.
"Obviously, I'd prefer to be a little further up, but all in all I think we should be pretty happy."
