The 21-year-old told Sky Sports News: "All I can say is my apologies to Adrian.
"It was definitely a mistake. I didn't consider the amount of speed I had on the straight and I lost a lot of downforce into that corner and tried to my best to stop the car.
"I should have considered a little bit more distance to brake as I approached the corner and the car in front quicker than I expected. I had nowhere to go."
The Mexican has been handed a five-place grid penalty at next weekend's Bahrain Grand Prix for causing the crash.
