Marc Marquez continued to dominate the Moto2 class after setting the fastest time in first practice for the Grand Prix of Aragon. The Spaniard has beaten title rival Stefan Bradl in each of the last six races, winning five of them, and looks well placed to close the German's 23 point still further.
Aleix Espargaro was in particularly good form in the early stages, setting a 1:55.375 at the end of his first run to edge out Alex de Angelis and Bradley Smith. With seven minutes remaining, the in-form Scott Redding hit the front with a 1:55.173, forcing Espargaro back out in response.
The Pons Kalex rider was the first rider into the 1:54s but Marquez was going even quicker just behind him. Espargaro's 1:54.880 was immediately beaten as the Catalunya Caixa rider went 0.023s quicker, enough to finish the session on top.
Andrea Iannone delivered his quickest lap in the final minute to snatch third from Redding while de Angelis fell back to fifth. Simone Corsi was next up in sixth ahead of Anthony West who was an impressive seventh for the MZ Racing Team.
Once again, Stefan Bradl comes into the weekend under intense pressure and the championship leader could only make it up to eighth, doing so on the final lap of the session. Bradley Smith followed him in ninth while Yuki Takahashi rounded out the top ten.
At the other end of the timesheets, Elena Rosell made her return to the series after an unsuccessful wildcard appearance at Assen. The 25 year old brought up the rear in 39th but was over three seconds inside the 107% time, meaning she will almost certainly race on Sunday.
