Jonathan Rea completed the Misano World Superbike double after snatching victory from Michael van der Mark, while Marco Melandri was third in a thrilling Sunday race.
Barni Racing’s Xavi Fores took the holeshot into the first corner ahead of van der Mark on the Yamaha and Kawasaki’s Tom Sykes, while Rea scythed his way up to sixth from ninth.
A touch between Melandri and Lorenzo Savadori allowed Chaz Davies to leap ahead of them and Rea to fifth at the Carro hairpin, though Melandri would seize the place from his Ducati teammate after a small scrap at Tramonto on lap two.
Rea attempted to demote Davies further at Rio on lap three, but ran wide at the final part and allowed the Ducati rider back through.

Sykes succumbed to the advances of his KRT teammate at Turn 3 on lap seven, with Rea soon engaging with Melandri for second.
Melandri and Rea carved each other up across the eighth lap, with the Kawasaki rider taking second by jamming his ZX-10RR up the inside of the Italian at Carro.
