HIGHLIGHTS: See all the key moments from second practice in Barcelona
Lewis Hamilton has won the last four Spanish Grands Prix in a row – and in second practice for this year's race he was once again back at the top of the time sheets.
The reigning world champion had finished the morning session third fastest behind Mercedes team mate Valterri Bottas and Red Bull's Max Verstappen, but in FP2 he was back on top as he looked to dial in his W12 ready for tomorrow's qualifying session and the race on Sunday.
Hamilton's title rival Verstappen had a much scruffier session, aborting his quick run on soft tyres after running wide, and ending up only ninth quickest, one place ahead of his Red Bull team mate Perez.
