The track shall be artificially-dampened in order for teams to focus on Pirelli's Cinturato intermediate and full wet tyres.

Mercedes will once again rotate its drivers with Lewis Hamilton kicking off the day, followed by Valtteri Bottas in the afternoon.

Max Verstappen slots in at Red Bull, while Kimi Raikkonen takes over from Sebastian Vettel.

Stoffel Vandoorne is hoping that yesterday's day of clean running spills over to Thursday for McLaren.

Phillip van Osten

Motor racing was a backdrop from the outset in Phillip van Osten's life. Born in Southern California, Phillip grew up with the sights and sounds of fast cars thanks to his father, Dick van Osten, an editor and writer for Auto Speed and Sport and Motor Trend. Phillip's passion for racing grew even more when his family moved to Europe and he became acquainted with the extraordinary world of Grand Prix racing. He was an early contributor to the monthly French F1i Magazine, often providing a historic or business perspective on Formula 1's affairs. In 2012, he co-authored along with fellow journalist Pierre Van Vliet the English-language adaptation of a limited edition book devoted to the great Belgian driver Jacky Ickx. He also authored "The American Legacy in Formula 1", a book which recounts the trials and tribulations of American drivers in Grand Prix racing. Phillip is also a commentator for Belgian broadcaster Be.TV for the US Indycar series.
