India's Arjun Maini topped the time sheets on Day 2 of the FIA Formula 2 Championship post-season test at Yas Marina Circuit.
The Haas development driver carried this momentum into the morning session of Day 3, where he again claimed the top spot.
Driving the Russian Time's Artem Markelov's car, who finished second in the F2 Drivers Championship Series in 2017, Arjun topped the time sheets with a lap of 1:48.645 on Friday, and a 1:49.040 in Saturday's morning session.

The JK-Tyre and TVS Motorsport-supported driver finished fifth fastest in the morning session of Day 2 but lost his place in the standings after his car was found to be underweight by 1 kg and penaliised.
He dominated the next two sessions with impressive drives on both days. The testing will conclude on Saturday with the evening session at 20:00 (GMT+5:30).
The Indian had finished 10th on Day 1 of the testing.
