The Spanish rider was unstoppable on home soil, winning the Superpole race to give himself pole for the final race of the weekend, which he duly dominated, beating Yamaha's Toprak Razgatlioglu by eight seconds.
It gives Bautista, who signed a new contract to stay at Ducati ahead of the Barcelona weekend, a healthy 69-point advantage over nearest rival Razgatlioglu in the riders' standings.
