Oscar Piastri's hopes of backing up last year's Belgian Grand Prix podium took a significant hit on Saturday at Spa-Francorchamps, with the Australian McLaren driver qualifying seventh — and set to start sixth after grid penalties elsewhere — following a difficult weekend hampered by mechanical trouble and a persistent lack of pace. Meanwhile, a dramatic practice session crash from Lewis Hamilton kept Ferrari mechanics working against the clock, and 19-year-old Kimi Antonelli claimed pole position in a nail-biting finish over Max Verstappen.

Piastri's Tough Weekend: Hydraulic Leak, Gearbox Swap and Missing Speed

It was far from a straightforward build-up to qualifying for Piastri. On Friday, the McLaren garage was thrown into a scramble after a hydraulic leak emerged at the end of the opening practice session, forcing the team to carry out a gearbox replacement that cost the 23-year-old crucial running time on the iconic Belgian circuit.

The disruption carried over into Saturday, with Piastri admitting the car's balance had been troublesome throughout the entire weekend. Despite those difficulties, he fought his way into Q3, only to find he simply didn't have the outright pace to push toward the front of the grid.

"Just speed," Piastri said bluntly when asked what was missing from his package. "It's not been particularly easy all weekend to be honest, struggling with the balance of the car, but today in particular it's been a pretty big grind to try and get any lap time out of it — not an easy day, but we will see what we can do tomorrow."

Piastri assessed McLaren as likely the third or fourth-fastest car on track at Spa, though he expressed hope the team could still make its presence felt in Sunday's race.

The contrast with teammate Lando Norris was stark. Norris delivered a strong qualifying performance, briefly posting the fastest lap before finishing third overall — only to be handed a 10-place grid penalty for exceeding his power unit component allocation, dropping him to 13th on the grid for the race.

"We haven't changed anything, we are just quicker on this track," Norris said after qualifying, adding that it was "unfortunate" his genuine starting position wouldn't reflect his performance. He remained optimistic about Sunday's prospects nonetheless.

Hamilton's Crash: 'I've Destroyed the Car, Mate'

While the qualifying hour itself provided plenty of tension, the defining moment of Saturday at Spa came earlier during the third practice session, when Lewis Hamilton's afternoon turned to chaos at the Fagnes chicane.

The seven-time world champion ran wide through the chicane while trying to close on Antonelli, sliding into the gravel and slamming his rear wheel hard into the barrier. The impact shredded the tyre and caused significant damage to the Ferrari's rear wing, leaving the car beached and Hamilton climbing out to survey the wreckage.

Spectators in the grandstands surged toward the barriers to get a closer look as a yellow flag brought practice to a halt. Over the team radio, a rueful Hamilton delivered a message that quickly became the quote of the weekend: "I've destroyed the car mate, sorry."

Ferrari's mechanics responded with a remarkable turnaround, getting the car rebuilt and race-ready in time for qualifying that afternoon. Hamilton ultimately claimed sixth place on the grid — a solid salvage job given the circumstances, though not the result the team would have hoped for heading into the race.

Antonelli Holds Off Verstappen for Pole

At the front of the grid, it was Mercedes teenager Kimi Antonelli who delivered the standout performance of the day, securing his sixth career pole position with a lap of 1 minute 44.361 seconds — good enough to beat Verstappen by three-tenths of a second.

Verstappen, who benefited from a tow provided by Red Bull teammate Isack Hadjar, will line up second on the grid, with Norris's grid drop elevating others behind.

"To bring home pole is nice, but tomorrow is another day," Antonelli said. "With Max starting next to me, it will be important to get a good start and be ahead into Turn 5."

The Belgian Grand Prix gets underway on Sunday at 11pm AEST, with Spa-Francorchamps — the longest circuit on the Formula 1 calendar — promising its usual blend of high-speed corners, elevation changes and potentially changeable weather conditions.
