Mercedes rivalry heats up as Rosberg closes in on Hamilton

Nico Rosberg closed the gap on Mercedes team-mate and Formula 1 world championship leader Lewis Hamilton to 10 points with a dominant victory in the Austrian Grand Prix.

The German dived down the inside of pole-sitter Hamilton at Turn 1 to snatch the lead and despite suffering tyre vibrations in the closing stages he held on to take his third win of the year.

Hamilton, who had five seconds added to his race time for crossing the white line at the pitlane exit, finished second with Williams's Felipe Massa scoring his first podium of the year in third after Sebastian Vettel was delayed at his pitstop.
