Lewis Hamilton’s Italian Grand Prix went from bad to worse when he was penalized for contacting Oscar Piastri.
Both men were battling for eighth place at Monza with 10 laps to go when things got too tight around the fourth corner.
Hamilton positioned his Mercedes outside Piastri’s McLaren before the chicane.
But then they touched as they approached the corner.
Both riders managed to avoid a massive shunt, with Hamilton jumping past Piastri, before straightening past him.
Both men then went straight into the corner, with the young Australian suffering damage to the front wing which forced him to pit.
Speaking on team radio, Piastri said: “He just ran into me in the middle of a break-in.”
The stewards agreed, handing Hamilton a five-second penalty.
But that was cold consolation for Piastri who was seen shaking his head in his cockpit during a lengthy pit stop to repair the damage.
The 22-year-old finished 14th after undergoing a front wing change, and eventually finished 12th, while also taking the fastest lap of the race.
Meanwhile, Hamilton managed to convert a sixth-place finish despite the penalty.
