Toro Rosso debutant Daniel Ricciardo had to set aside his nerves as he took to the track in first practice in Australia.
The reserve driver piloted Jamie Alguersuari's STR6 in the first session for 23 laps and clocked a time only one-tenth off of team-mate Sebastien Buemi.
Ricciardo admitted that he had to settle down into the car before punching in some good lap times but was happy with his first taste of F1 action.
He added: “All week I was trying to prepare myself, to have the least amount of nerves and pressure as possible.
“When I pulled out of the pits and onto the track, I felt a little bit jelly-like for the first few corners. But once we got the procedural stuff out of the way, I was pretty happy and got into it.
“The first important thing is that I brought the car back in one piece, so hopefully the team is happy with that and afterwards I was just trying to build up gradually and learn.”
Alguersuari will have to get used to seeing Ricciardo in his car for first practice but the young Spaniard is delighted his team are giving another young driver a chance in F1 and was pleased with how the morning went.
He said: “It was a different day, as I had to get used to seeing Daniel driving my car in the morning! I am cool with it and it's good that another Red Bull young driver gets the chance to experience Formula 1.
“However, I am happy with the feel from the car, it seems to be competitive and even though it went well today, there is the potential to get much more out of it tomorrow.”
Toro Rosso's times place them firmly in the middle of the pack and Buemi believes that they are in a tight pack and with a little bit of extra work can push on up the field.
He finished: “Currently the times show us in the middle of the pack, in a tight group in terms of lap times of those ahead and behind us.
“We need to get the maximum out of this evening if we want to get the maximum out of tomorrow.”
