GP3 Series runner-up Alexander Albon set the pace on the second day of the post-season GP2 test at the Yas Marina Circuit in Abu Dhabi.
Albon, testing with ART Grand Prix, narrowly edged Raffaele Marciello (Trident) and Charles Leclerc (Prema) in the afternoon session - but came up short of beating Marciello's Wednesday benchmark.
Renault protege Oliver Rowland, third quickest on Wednesday, set the pace in the morning session of the second day, edging out Marciello by 0.037s.
Rowland's lap, however, was slower than both the session-toppers from Wednesday, and the DAMS driver was surpassed soon after the midday break.
Ferrari junior Leclerc, who was among the three drivers to stop and cause a red flag in the morning session, led the afternoon early on, before being overhauled by Jordan King (MP Motorsport) and Marciello with one hour left on the clock.
Marciello and Leclerc then cleared King, but were both overtaken by Albon, who ended the day on top.
King was fourth, while Johnny Cecotto (Rapax) took fifth from Racing Engineering tester Louis Deletraz, who was followed closely by Rowland and DAMS teammate Nicholas Latifi.
Despite causing two stoppages, Ferrari protege Antonio Fuoco (Prema) ended the day in ninth, with fellow rookie Nyck de Vries (Rapax) making up the top 10.
