Daniel Ricciardo insists that he wasn't aware of the queue of cars that were slowing in sector 3 at the end of Q1.
Ricciardo formed onto the back of the queue as a handful of drivers looked for clean air before setting their times before the chequered flag fell.
While he cleared Grosjean, he went side-by-side through the last corner with Perez, with both failing to improve their lap times, eliminating them from Q1.
"We got a bit caught up at the end of the lap there," Ricciardo said. "I was just speaking to the engineers now and I was told that I had quite a buffer to the chequered flag, so I knew I could have gone slower.
"But what I didn't expect was the train of cars at the final corner. At the time I wasn't aware of the number of cars that were yet to start their laps so I kind of went on my pace, to keep the tyres in."
"By the time I got to the last sector I saw everyone. I was a bit mixed, do I slow down and let the tyres cool too much? I saw Lewis go, he went through and got a clear gap. So I thought I'm going to go.
"I got Grosjean and I thought I could get Perez but we just went side by side through the final corner.
"All of that is irrelevant, to be honest. I probably could have done better on the out lap phase, but it's just awareness of where everywhere was."
