"That was really stressful. But luckily, I got away with it. There was a TV when it went green, so perfect. The rest of the race was smooth sailing, but I had a fast Jehan Daruvala following me. It wasn't that easy."
The win was his first since winning the sprint race one in Saudi Arabia last December, and his second for his Formula 2 career.
But for the highs of the sprint race, the lows of the feature race were just as significant for the Kiwi contingent, with Armstrong finishing 16th, while Carlin's Liam Lawson was first out late in the race after a heavy crash into the hoardings.
There was plenty of carnage early in the race, and that worked in favour of those who started on the super-soft compound tyres, who were afforded an early pit stop eight laps in when a full safety car was on the track.
Drivers can't pit under a VSC, but are allowed to do so under the full safety car, and most of those with the super-soft tyres changed to the medium. Unfortunately for both Lawson and Armstrong, they weren't among them.
"I guess now we need another safety car, right?" Lawson asked his team over radio, resigned to the disadvantage they were now under.
The strategy deployed by both Kiwi drivers – starting the race on the medium tyres and pitting around the 20-lap mark – placed them toward the back end of the field after their stops.
Unfortunately, there wasn't another safety car before that point but one on the track soon afterwards – of no help to the Kiwis.
Armstrong fought on to finish in 16th, while Lawson's crash on lap 32 brought out another safety car which allowed eventual winner Théo Pourchaire a couple of victory laps – with no overtaking allowed while the safety car is on the track.
Fortunately for both Armstrong and Lawson, the rough feature race didn't impact their overall standings too much. After three events on the calendar, Armstrong sits seventh on the leaderboard with 30 points, while Lawson is fourth with 35 points. Pourchaire leads the way with 52 points.
