Reigning world superbike champion Tom Sykes looks set to extend his lead in the championship after taking pole position in Portugal.
The Kawasaki rider saved his best until the final moments of the session at the Portimao circuit posting a 1.42.484s effort which was good enough for his 22nd pole of his career.
The session proved to be hard fought with Rea, Loris Baz and Sylvain Guintoli all enjoying spells at the top of the timesheets before Sykes struck.
Marco Melandri will start from fourth with the Italian joined on the second row by Baz and Guintoli as the trio were covered by less than a tenth of a second.
Crescent Suzuki's Eugene Laverty was seventh narrowly ahead of Ducati's Davide Giugliano.
The second Pata Honda of Leon Haslam claimed ninth on the grid while EVO rider Sylvain Barrier rounded out the top 10.
Australia's Bryan Staring will start Sunday's two races from 17th position for the IRON BRAIN Kawasaki Team.
Sykes holds a 39 point lead over Guintoli heading into this weekend's meeting at Portimao.
