BARCELONA, Spain -- Lewis Hamilton topped second practice for the Spanish Grand Prix with a time 0.090s clear of Mercedes teammate Valtteri Bottas.
After Mercedes dominated the opening practice session on Friday morning, Ferrari closed the gap to 0.310s in the afternoon as all the teams sampled the soft compound tyres for the first time. Kimi Raikkonen was the fastest of the two Ferraris by 0.108s but was still 0.220s off Bottas in second.
Most of Mercedes' advantage was found in the final sector, which consists of slower corners and requires good traction. Sebastian Vettel was fastest in the high-speed corners of sector two, but was 0.
