(CNN) Mercedes driver Valtteri Bottas won the Azerbaijan GP to move clear at the top of the drivers' standings after four races of the 2019 season.

The Finnish driver now has two wins and two second-place finishes but sits above teammate Lewis Hamilton, courtesy of a bonus point he claimed by recording the fastest lap in Australia.

Hamilton, who finished second behind Bottas, capped off a good day for Mercedes, which extended its lead at the top of the team championship to 74-points.

It was the fourth Mercedes one-two finish of the season, an all-time record in the sport.
