Sergey Sirotkin finished 15th and Lance Stroll 16th in the United States Grand Prix. Both drivers started the race on the supersoft Pirelli tyre, with Sergey P14 and Lance P15 on the grid.

Both cars suffered damage after each making contact with a different McLaren on the opening lap, with Lance receiving a drive-through penalty for causing a collision as a result.

Lance immediately pitted for a nose change and swapped to the soft tyre, and came back out in P18, before pitting again on lap 38 for the ultrasoft tyre.

Sergey ran as high as P11 in his opening stint before the Virtual Safety Car was deployed after Ricciardo stopped on track, prompting Sergey to pit for the soft tyre. He made his second and final stop on lap 29 for the supersoft tyre.

Paddy Lowe, Chief Technical Officer: It was a tough day. The race could have been quite promising but it all went wrong for Lance in the first few corners where he had contact with Alonso from which we had to change his front-wing. He subsequently received a drive-through penalty for this incident. The car was also damaged beyond the front-wing, so Lance ran a fairly lonely race out on his own at the back of the field. In Sergey's case, he also had damage after contact with Vandoorne in turn 11 of the first lap which lost him a significant amount of downforce. Although his position looked quite promising through the first stint, we took the opportunity to stop under the Virtual Safety Car which should have been a good strategy but nothing worked today because the pace of the car was not there to compete. That said, we did get both cars home so well done to all the crew for another good job operationally. These aren't the finishing positions we hoped for today and so we look forward to a better result in Mexico.

Sergey Sirotkin: It was a tough race. I had a very good start and gained quite a lot of places. I got some damage on the rear-side of the floor in one of the incidents with a McLaren through the first-lap, but everything was ok whilst we were in dirty air and there was a lot of inconsistency in the things happening around the track. I had good pace considering the damage and I could keep up with the cars ahead and everything looked good. After the pitstop it just didn't work. When everyone got into their rhythm and got into their pace we just didn't have the performance to compete and keep the people behind. The damage on the floor that I had was probably painful for us in clean air when everyone could use their performance a bit more. I was just basically trying to get to the end without losing too many places which was not the best feeling either. I don't think we could have done much better.

Lance Stroll: It was a terrible day. I had contact with Alonso on the first lap in turn five. I saw a gap and went for it, but I don't think he really saw me and turned in. After that my race was finished as I got the drive through and that was that. I haven't seen the footage, but I think it was a racing incident. I am just disappointed about the result.
