Davide Giugliano has led the Aruba.it Racing Ducati comeback at Laguna Seca by topping warm-up ahead of yesterday's race winner Jonathan Rea.

Rea, less than one-tenth off of the Italian, secured second on the timesheet ahead of Davies with Tom Sykes edging Pata Yamaha's Alex Lowes.
Rostrum finisher in race one Nicky Hayden will be keen to repeat the feat and claimed sixth in warm-up ahead of top BMW rider Jordi Torres as Xavi Fores, Michael van der Mark and Leon Camier rounded out the top ten.
