"I was closing up little-by-little on each lap. We'd seen a small amount of tyre degradation during the feature race so I was being sensible. I got by Alexander Rossi and started to close on Marciello.
"A dive bomb on him on the last lap almost came off. It was a shame we didn't get on the podium but we took good points from both races in Austria. It was a missed opportunity, yet there are lots of positives - we've found more speed in the car and we are getting more competitive.
"We don't have the fastest car yet; but we are making progress. I'm looking forwards to the British Grand Prix round at Silverstone in two weeks." said Evans.
Johnny Cecotto Jr won race eight of the GP2 Series on Sunday morning, holding off Stefano Coletti by 0.742s in a thrilling encounter. Cecotto stormed into the lead from the second row at the start as poleman Rossi and fellow front-row man Evans (Russian Time) made poor starts.
Cecotto's first challenge came from Rossi, who shadowed him over the opening five laps. However, Rossi fell back into the clutches of Marciello, who had ended the opening lap in fourth.
Marciello passed Rossi for second on lap seven, and closed right up to race leader Cecotto. In spite of hounding him for several laps, Marciello's tyres went off, and he fell back. Coletti, meanwhile, passed Rossi for third on lap 17, and then repassed Marciello for second two laps later.
Cecotto's three-second lead quickly disappeared as Coletti cut the gap, but he could not find a way past. Marciello clung to third, despite a couple of lunges from Evans in the closing stages. Rossi finished fifth.

It was Cecotto's second win of the season and puts him third in the points race. Series leader Jolyon Palmer, who finished sixth, extended his lead over Felipe Nasr to 33 points. Nasr was an early retirement with a clutch problem.
Julian Leal was seventh, after being pushed into the run-off by Palmer on lap 20 after they had swapped positions a number of times.
