The second race of the day at Portimao was held in tricky conditions as the rain which began during the Supersport race continued to fall at the Portuguese circuit.

Jonathan Rea (Pata Honda World Superbike Team) romped home after a reduced race distance of 18 laps as the winner after Sylvain Guintoli (Aprilia Racing Team) and his team mate Marco Melandri collided at turn five in the closing stages. Guintoli was able to remount eventually finishing 7th.

Behind Rea, Davide Giugliano (Ducati Superbike Team) was a lonely 2nd with Chaz Davies (Ducati Superbike Team) snatching the final podium spot from Alex Lowes (Voltcom Crescent Suzuki) and Leon Haslam (Pata Honda World Superbike Team) after an enthralling final few laps in which 3rd position changed several times.

Loris Baz (Kawasaki Racing Team) finished sixth.

Race one winner Tom Sykes (Kawasaki Racing Team) finished race two a lowly 8th after dropping back through the pack. He was passed on the penultimate lap by the recovering Guintoli who salvaged 7th at the flag.

In the EVO battle the honours in race 2 went to Sylvain Barrier (BMW Motorrad Italia), the Frenchman finishing 11th overall.
