Lewis Hamilton will have his work cut out for him in Sunday's US Grand Prix after the Mercedes driver suffered a shock exit from qualifying in Q1 at The Circuit of the Americas.
The seven-time world champion, who had shown promising pace earlier in the weekend, found himself unable to match the speed of his rivals, ultimately qualifying 19th in a dramatic turn of events.
Hamilton blamed a front suspension issue in Saturday's Sprint event that led to a set-up change for his disappointing performance.
The Briton had delayed his final flyer until late in the Q1 segment, leaving it to the last moments to secure a place in Q2.
However, his lap began to unravel as he entered Turn 12 at the end of the long back straight. He struggled with braking, ran deep into the corner, and fought to regain control as the car suffered snap oversteer on the exit.
As a result, his middle sector time was significantly slower than that of his teammate, George Russell, and he couldn't recover the lost time.
"I mean, it's been pretty terrible. The car felt great yesterday, so I obviously came really optimistic for today," Hamilton explained.
"[In the sprint] something failed in the front suspension, literally as we pulled away from the line for the formation lap, and I did that through the race.
"They figured that out, they changed the corner, but it felt like a mess throughout quali."
Elaborating further on his plight, Hamilton suggested that Mercedes might need to start his car from the pitlane for Sunday's race to allow his crews to make changes to his W15 and give him a fighting chance, given the car's unbalanced state.
"We should probably start from the pitlane," he said. "Because otherwise I won't be going anywhere from where I am. It's just a very inconsistent balance and no grip."
Should Hamilton nevertheless opt for a normal start on Sunday, he'll gain at least one spot on the grid due to Red Bull's Liam Lawson taking a back-of-the-grid penalty for exceeding his power unit allocation.
Regardless, the Mercedes driver's path to a strong result in Austin will still be a tough uphill battle.
