Márquez fastest as Rossi returns at Aragón
22 September 2017 – Marc Márquez topped a wet opening practice session for the Aragón Grand Prix, as Valentino Rossi returned to action following a double leg break.
Márquez was already leading when he pumped in two quick times late on, as the track slowly dried, ending up with a 2:01.243, half a second clear of Honda team-mate Dani Pedrosa.
Much of the attention was understandably on Rossi's return, the Yamaha rider back on his MotoGP bike just 22 days after sustaining the aforementioned injuries to his right leg.
Rossi briefly spent a phase in the top 10, looking relatively comfortable out on track, and completing eight laps, before returning to the garage to talk with engineers.
As rivals improved, Rossi fell to 18th, around three seconds off the pace, but he still finished ahead of team-mate Maverick Viñales, who started the weekend in 20th.
Tech 3 Yamaha's Johann Zarco finished closest to the works Honda pair, followed by Jack Miller (Marc VDS) and Mika Kallio, who is making another wildcard appearance with KTM.
Jorge Lorenzo led Ducati's charge in sixth, in front of LCR Honda's Cal Crutchlow, Pramac's Danilo Petrucci, Suzuki's Andrea Iannone and team-mate Andrea Dovizioso.
Dovizioso heads into the event tied on points with Márquez at the top of the standings, though the latter leads on countback of number of second place finishes.
There were no major incidents during the 45 minutes of running, though KTM's Bradley Smith ground to a halt due to a technical problem, leaving him without a time.
Friday's second practice session at Aragón will begin at 14:05 local time
