Australian driver Daniel Ricciardo claimed his first podium finish in Formula One as the Mercedes team dominated the Spanish Grand Prix on Sunday.

Lewis Hamilton took over the championship lead by winning his fourth straight race ahead of Mercedes teammate Nico Rosberg.

Ricciardo was third in his Red Bull followed by his four-time world champion teammate Sebastian Vettel.

Ricciardo finished the season-opening Australian GP in third place but had the result taken away by a technical infringement by his Red Bull team.

Hamilton's 26th career win gave him 100 points after five races, three more than Rosberg, who closed to within one second of his teammate late but again couldn't find his way past his main rival.

Hamilton hasn't led the championship since June 2012 after winning the Canadian GP with McLaren.
