Joan Lascorz is edging closer to the Portimao lap record after topping the second test outing of the day for the World Supersport competitors.
The Spaniard was almost 1.4secs quicker than his morning effort to set a benchmark of 1min 45.292secs, Lascorz now just half a second off Cal Crutchlow's lap record with two days of testing remaining.
Once again, Michele Pirro was second fastest, the Italian making an impressive full-time debut with Ten Kate Honda in the absence of team-mate Kenan Sofuoglu to get to within three tenths of Lascorz.
The biggest improver over the course of the day, however, was Miguel Praia, the Portuguese rider using his local knowledge to good effect to slice almost four seconds off his AM time to go a strong third fastest.
It meant he was once again quicker than his Parkalgar Honda team-mate Eugene Laverty, the Irishman settling back into competition having not ridden the bike since he won the 2009 season finale at Portimao almost three months ago.
Katsuaki Fujiwara was fifth on the second factory-backed Kawasaki, ahead of Chaz Davies, who was once again the fastest Triumph rider, while Fabien Foret, David Salom, Danilo Dell'Omo and Jason Di Salvo rounded out the top ten.
