With Friday afternoon practice cancelled due to power cuts, Marc Marquez finished day one of the Aragon Moto2 Grand Prix on top of the timesheets.
The Repsol Suter rookie, who has now reduced Stefan Bradl's title lead to 23 points, finished morning practice just 0.023sec ahead of countryman Aleix Espargaro (Pons Kalex) with Italian Andrea Iannone in third for Speed Master Suter.
Marc VDS rider Scott Redding continued his recent momentum with fourth, ahead of Alex de Angelis (MotoBI), Simone Corsi (FTR) and a surprise showing from Anthony West (MZ-RE Honda).
Bradl, beaten by Marquez in the last six rounds, could only manage eighth, 0.774sec from the top.
