Tom Sykes ended the first day of World Superbike free practice at Jerez on top as his time from FP1 was good enough to maintain his narrow advantage over team-mate Jonathan Rea.
Alex Lowes was one of only two riders inside the eventual top ten to better his morning time, the Englishman topping the afternoon session and jumping up the overall order to third with his final lap of the session.
Indeed, Lowes' best time was just 0.09s off Sykes' fastest time of the day, meaning the front three and Ducati's Chaz Davies were separated by just 0.099s at the close of the day.
Sykes couldn't be truly happy however, as he was caught out by an early fall at the tight and treacherous turn two just three minutes into the session. The Englishman consequently lost 20 minutes of track time as repairs were made to his bike.
Unable to carry out tests over race distance, Sykes acknowledged his pace over race distance remains a concern as he managed just three laps in the low 1m 42s in FP2. In contrast Rea, ever the model of consistency, posted seven laps in the 42s on his first run during the 45 minutes.
Davies remained fourth, a place ahead of Niccolò Canepa, whose impressive morning time kept just 0.168s between him and Sykes' best.
Like Lowes, Jordi Torres was another afternoon improver but that came at a price. The Spaniard crashed in the same place as Sykes after losing the front of his Aprilia RSV4 in a spill that had striking similarities to his morning effort, which befell him at turn one.
Leon Haslam followed in seventh as neither he, the Ducatis of Matteo Baiocco and Michele Pirro, nor the Pata Hondas of Sylvain Guintoli or Michael van der Mark lapped faster in the afternoon.
Outside the top ten, Leon Camier placed 15th after setting a time of 1m 43.160s, 1.2s slower than Sykes.
It was an eventful afternoon for Grillini Kawasaki's Alex Phillis. The young Australian crashed twice, once at turn two, and ended the day 22nd overall.
