Mercedes in the mood for Shanghai showdown

MELBOURNE - Lewis Hamilton's Mercedes vowed to come back hard in China after being ambushed by resurgent Ferrari in Formula One's season-opener in Australia on Sunday.

The German team, which has ruled F1 for the past three years, got a rude awakening as Ferrari's Sebastian Vettel beat second-place Hamilton by almost 10 seconds in Melbourne.

Three-time world champion Hamilton was runner-up in last year's championship to his now-retired former team-mate Nico Rosberg.
