I think Aston Martin tried to save a set of tyres, Stroll went out and Alonso also fell right down.
As soon as Alonso goes out in Q2 with a fresh set of boots on, he's able to pump in a much more respectable time.
They got greedy with Q3 options and now one of their cars is not going to feature at all.

12. Lewis Hamilton

Better from the Alpines. Australia and Baku were weekends to forget but Esteban Ocon clocks a time half a second away from Max Verstappen's top marker and lifts his car up into fourth. Pierre Gasly comes through next and sits in fifth.

Alonso, who was a man who had to step up, has just found a heap of performance - Better from Aston Martin.
The two Mercedes are over a second off the pace of Max Verstappen. That W14 is going to have to put in a solid shift to lift Lewis Hamilton and George Russell into to Q3 and avoid any shocks.
Soft tyres are bolted on across the remaining competitors' cars.
World champion Max Verstappen crosses the line and is goes into the 1:27s. Sergio Perez is two tenths behind and Fernando Alonso is sitting in third.
Right then, what will this second session bring us? The Red Bull of Max Verstappen, complete with fan-designed livery, is one of the first cars out on track.

Q2 is under way.

Andrew: That was a breathless Q1 session. The make-up of the grid between 3rd and 14th is anybody’s guess.
Logan Sargeant sounded shocked when he was dropped in P20. "It was very tight," his engineered explained. The search for his first F1 points is going to be a very difficult task tomorrow.

Stroll is the big shock there, At times Aston Martin have had the second fastest car this year. Alonso in 12th. They don't have a huge deal of pace here.
16. Lando Norris (McLaren)
17. Yuki Tsunoda (Alpha Tauri)
18. Lance Stroll (Aston Martin)
19. Oscar Piastri (McLaren)
20. Logan Sargeant (Williams)
George Russell is safe and goes 11th fastest. Mercedes just need Lewis Hamilton to find a spark in his W14.
Saved. Hamilton is through, knocking out Lando Norris. His McLaren team-mate is also given the boot.

It is going to come down to one flying lap for everyone.
Stewards have noted the incident between Zhou Guanyu and Carlos Sainz.
McLaren's Lando Norris goes up to 12th but isn’t safe just yet.
Oscar Piastri has now joined his McLaren team-mate Lando Norris in the drop zone.
George Russell and Lewis Hamilton need to pull a rabbit out the hat here. There are 19 cars out on track. The traffic isn't going to ease any time in the next few minutes.
"Traffic is ... stressful. Just tell me the gaps as soon as I cross the finish line. That's the only thing I want to know."
