MONZA, Italy (AP) Max Verstappen raised eyebrows again in the final practice session for the Italian Grand Prix on Saturday, while Mercedes teammates Lewis Hamilton and Nico Rosberg were once more 1-2.
After tangling with Ferrari cars in last weekend's Belgian GP, the 18-year-old Verstappen put his Red Bull in the way of Rosberg on the Monza circuit.
Verstappen was on a slow lap when he veered into the racing line, resulting in Rosberg nearly rear-ending him.
''What on earth was that?'' Rosberg said on his radio as Verstappen waved to apologize.
Later, Verstappen was blocked by Kevin Magnussen's Renault, bouncing him wide.
Hamilton was nearly four tenths faster than Rosberg, with Sebastian Vettel nearly a second behind in his Ferrari.
Verstappen placed eighth.
Qualifying is scheduled for later, with the race Sunday.
