IMOLA, Italy (Reuters) -Haas have asked Formula One's governing body for written clarification of a decision that consigned Oliver Bearman to last place on the starting grid for Sunday's Emilia-Romagna Grand Prix.

Bearman would have made the second phase of qualifying but had his fastest lap deleted when he crossed the line a fraction after the session was stopped due to Franco Colapinto's heavy crash.

The British rookie qualified 19th as a result, that turning out to be the last place on the grid after Red Bull rebuilt Yuki Tsunoda's crashed car and were obliged to start the Japanese driver from the pit lane.
