Red Bull junior Pierre Gasly topped the timesheets on the second GP2 pre-season testing day at Catalunya.
Although the?Prema driver was narrowly beaten by?Sergey Sirotkin in the morning, Gasly went on to improve the benchmark by further two tenths in the afternoon.
The Russian set his time of 1m27.971s in the early parts of morning practice?and stayed first for the rest of the session, which was once interrupted by Antonio Giovinazzi stopping on track.
He was just a tenth quicker than Gasly, the Frenchman?beating Racing Engineering duo Jordan King and Norman Nato to the spot.
Raffaele Marciello and Mitch Evans ended up fifth and sixth respectively, followed by the Carlin of Rene Binder, who replaced William Buller at the team.
Former GP3 rivals Marvin Kirchhofer and Luca Ghiotto were separated by just 0.011s in eighth and 10th as Artem Markelov took ninth.
Being?one of few drivers able to match their morning pace, Gasly topped the second session by more than a second.
King maintained his strong form to take second, followed by Arthur Pic.
Giovinazzi took fourth, ahead of MP drivers Daniel De Jong and Oliver Rowland.
Binder once again made it to the top 10 in seventh, ahead of Jimmy Eriksson, Gustav Malja and Ghiotto.
After being absent?yesterday, Status kicked off his testing programme with Meindert van Buuren and Sergio Canamasas.
