Hamilton's back was "a real mess" after aborted long run at Baku

Hamilton and Mercedes teammate George Russell have experienced excessive porpoising and bottoming at the Baku street track, with the latter especially complaining that it has affected his visibility at the end of the straight.

Hamilton acknowledged that he wasn't able to complete a planned long run on Friday, which meant that the team didn't get all the data that it wanted.

He also noted that after overnight changes on the car on Saturday the porpoising had moved from the end of the main straight to the fast kinks at the beginning of it. He qualified seventh, two places behind Russell.

"Honestly, we had so much bottoming at the end of the straight yesterday that I couldn't finish my long run, my back was a real mess," he said.

"Thank God for Angela [Cullen]. I've got Angela to give me physio every night, and acupuncture. I woke up with quite a bit of pain this morning.

"And now we don't have it as bad at the end of the straight, but it's through those corners. You're just trying to keep it out of the wall. So with heavy fuel hopefully it will be less I'm hoping tomorrow, but we are very slow on the straight.

"So I'm sure part of that is the bottoming, because it slows you down every time you touch the ground. But the others also have like a Monza wing I think here, so we have a lot of work to do."

Hamilton indicated that just staying on the track was an even bigger concern that visibility.

"The visibility has been the same for us all year," he noted. "So definitely tough. For me, it was just keeping the thing out of the wall on the fast, high speed curves, but nothing we seem to do, like we changed so many different things, we just can't seem
