Carlos Sainz has vowed to learn from his own mistakes after a lock up on his one flying lap in Q2 cost him a place in the final shoot-out.
Although Sainz appeared to have the pace in his Toro Rosso to book a top ten position on the Sepang grid, a lock up on his flying lap in Q2 meant he was P15 when the rain came.
Quickly turning into a deluge, Sainz and his rivals were unable to run again and the rookie driver was left down in 15th place.
"Very disappointed," the Spaniard told the BBC.
"Q3 today was more than possible, even something more than getting through into Q3 – a good qualifying position.
"We did a big step forward from FP3 to qualy. We were looking very good, very sharp.
"But I have to say I made a rookie error in Turn 14, I locked up as a bit of rain started to drizzle.
"I went a bit straight and I lost that qualy lap."
He added: "These things can happen if you are a rookie and I'll learn from that mistake and keep moving forward."
Asked if he was looking forward to making up positions on Sunday he said: "You can only imagine."
