Gary Paffett and Rene Rast shared the spoils in DTM at Zandvoort.
Paffett held onto pole to lead the early laps of the opening race and reclaimed the advantage in the closing stages to take the win.
Rast had headed the race courtesy of leaving his stop until the last possible moment, but ultimately tumbled down the order when he eventually stopped.
With Paul Di Resta second, Lucas Auer third, and Pascal Wehrlein fourth it was a race dominated by Mercedes-AMG.
In Race 2, Rast dived in for his stop at the end of the opening lap before feeding back out into what would become the race lead once those ahead had served their stops.
A mid-race restart when Bruno Spengler spun saw Rast hold onto the lead to take his first win of the 2018 season.
Paffett trailed the Audi driver home in second, extending his championship lead, with Di Resta third.
Brands Hatch hosts the next DTM round on August 11-12.

Mir passed Marini on Lap 5 before KTM Ajo rider Binder got both on Lap 10.
Despite the tight margins, the South African was fairly comfortable at the front as Mir and Marini battled each other.
Binder’s team-mate Miguel Oliveira was 12th at the end of Lap 1 after nearly going down at Turn 13 but salvaged fourth.
