OSCHERSLEBEN, Germany — The teenage son of former Formula One champion Michael Schumacher made a strong debut at Formula 4 level Saturday. After starting in 19th position for the Van Amersfoort team, Mick Schumacher finished ninth to earn the best rookie award. The 16-year-old Schumacher says in comments reported by news agency dpa, “Of course I'm happy that I could catch up. I didn't even think that I was best rookie. After my qualifying yesterday and starting position I'm really satisfied.” It was the first of three races on the season-opening weekend. His father won a record seven Formula One titles and 91 Grand Prix in a stellar career. Michael is still recovering from serious head injuries suffered in a skiing accident on Dec. 29, 2013. — AP
