SPA, Belgium (AP) β Lewis Hamilton posted the fastest time in the second practice of the Belgian Grand Prix on Friday, finishing ahead of Mercedes teammate Nico Rosberg as their positions from the morning session were reversed.
Conditions were cool and overcast for both runs, although the rain stayed away on the 7-kilometer (4.3-mile) Spa track β the longest on the calendar.
Two-time F1 champion Fernando Alonso was third quickest both times in his Ferrari.
Four-time defending champion Sebastian Vettel sat out the second session because of a power unit failure due to an electrical problem in the morning, where he finished nearly two seconds behind Rosberg in 11th.
The red flag came up twice in the afternoon session. Venezuelan driver Pastor Maldonado lost control of his Lotus and Mexican Esteban Gutierrez stalled his Sauber.
