Chaz Davies (Aruba.it Racing - Ducati) secured his second win of the Motorland Aragon WorldSBK weekend, by 6.471 seconds from Tom Sykes (Kawasaki Racing Team).
Jonathan Rea (Kawasaki Racing Team) was third but looked to be on course for second place until he ran wide and Sykes pounced on his chance.
Sykes had made his usual fast start but Davies made a hard push in the first two laps to lead. Just after the halfway point Rea passed Sykes for second, as Sykes ran wide into the final corner, but it was not to last.
Behind the podium places Xavi Fores (Barni Racing Team Ducati) had another storming ride for his second fourth place of the weekend, just 2.2 seconds from Rea.
Michael van der Mark (Honda World Superbike Team) was having a top five ride until Jordi Torres (Althea BMW Racing Team) passed him. VDM would eventually slow to finish seventh.
Davide Giugliano (Aruba.it Racing - Ducati) had a disappointing race, with a mid-race hiccup dropping him back, although he rallied to finish sixth.
Alex De Angelis (IodaRacing Team Aprilia) was eighth, only a few days after arm surgery. Alex Lowes (Pata Yamaha Official WorldSBK Team) was ninth, winning a late battle with his team-mate Sylvain Guintoli (Pata Yamaha Official WorldSBK Team).
Josh Brookes (Milwaukee BMW) was 13th. Just out of the points, Leon Camier (MV Agusta Reparto Corse) went 16th.
Nicky Hayden (Honda World Superbike Team) was in trouble from the start and slowed dramatically, looking at the front end of his machine on lap 15, then pitting.
In the championship points Rea leads with 131, Davies is second on 105 and Sykes is third with 102.
