Tom Sykes eased to victory in the first race at Imola to drastically close the gap on championship leader Sylvain Guintoli after the Frenchman was forced to retire due to a mechanical problem on lap six.
Guintoli held a 28 point lead prior to race one, but his retirement and Sykes' victory has now closed the gap to just three points.
After setting a blistering time in superpole yesterday Sykes was fourth on the first lap, but worked his way up to the front by lap six and slowly edged away from the rest of the field.
Althea Aprilia rider Davide Giugliano led the first few laps after Jonathan Rea ran wide and onto the gravel on the first lap.
Giugliano stuck with Sykes for a number of laps but ultimately was unable to keep pace with the Kawasaki rider. Giugliano finished second.
Factory Aprilia rider Eugene Laverty completed the podium in third.
After Rea's off track excursion on lap one the Pata Honda rider rejoined in 11th place and by lap eighteen had passed Marco Melandri to take fourth.
Rea was looking good for a podium behind Laverty but crashed out with just two laps remaining on lap 19.
