So why did Mercedes not pit sooner or try to maintain him out all the best way to the top? And why have been the situations so laborious to foretell?

Mild drizzle fell all through the day at Istanbul Park, which means all drivers took intermediates for the beginning of the race to greatest sort out the damp situations.

Some groups believed the monitor would dry out inside 20 laps, however gentle rain continued to return down, which means it was laborious for drivers to discover a drying line.

Leclerc now discovered himself main after maintaining with Bottas and Verstappen within the opening stint. Ferrari was aiming to go the entire race with out making a pit cease.

It was the identical tactic Mercedes thought-about for Hamilton. He was now as much as fourth place, and informed Mercedes over the radio that he didn’t need to pit as his tempo nonetheless felt OK. The workforce agreed to maintain him out longer, giving itself extra pondering time and the possibility to probably save a pit cease if the monitor dried out for slicks within the closing phases.

However may Hamilton have held on to 3rd had Mercedes not pitted him?
