Antonio Giovinazzi has apologised to the Sauber team after he crashed out for a second time in as many days in China.
The Italian, standing in once again for Pascal Wehrlein, was impressive in the season opener in Australia, but he undid a lot of his hard work with two costly crashes in qualifying and the race itself.
"It was not my weekend," Giovinazzi said after the race. "I make the first mistake in qualifying and today I just called [for] dry tyres too early.
"When I come back on the track, when I went on the main straight, I just had some aquaplaning and lost the car straight away, nothing [I could] do.
"I want to first of all say sorry to the guys, to the team, because they did a fantastic job all night to rebuild the car for today. So, sorry I make this mistake.
"What's important now is to cancel from my mind this weekend and keep working, and hope I can be back strong for the next time."
Wehrlein is expected to return to the Sauber car for this weekend's Bahrain Grand Prix.
