Daniel Ricciardo admitted he was frustrated with himself for first-lap errors after finishing only eighth in the Austrian Grand Prix.
Red Bull's Canadian GP winner qualified fifth in Austria, but fell to 10th on the opening lap.
"It was frustrating - it's never nice going backwards on the first lap," said Ricciardo.
"Off the line it was actually one of our better starts - we were pseudo-competitive, though Kevin [Magnussen] was better.
"I basically tried to hang around the outside and it was the wrong thing to do as if you get on the other side of that sausage kerb, you just lose too much on the exit.
"So I got swamped onto that long straight and we struggle too much on the straights as it is.
"I was frustrated with myself for that. I'll have to see if I should've cut to the inside and got something better."
Ricciardo got back up to eighth by passing Nico Hulkenberg's Force India with a dramatic move around the outside at Turn 4.
"The last lap move put a smile on my face, but otherwise it was a pretty sad race," said Ricciardo.
"I hadn't really done anything good all day so I figured I had to do something.
"Ninth is not a familiar position for us this year, so in my mind I didn't have much to lose.
"I got in his tow, got close enough and thought 'what the hell, let's go for it'."
The other Red Bull of Sebastian Vettel slowed on the first lap with an apparent electrical problem, resumed running but retired after a collision with Esteban Gutierrez meant a new front wing was required.
Vettel confirmed that Red Bull parked the car to save mileage as he was too far behind the field to regain much ground.
"Sometimes you find yourself without problems, other times you have a lot of problems," he said.
