Max Verstappen was quickest earlier - isn't he always - but had spent much of the session at the other end of the timesheets as he focussed on the hards.
Piastri was second, ahead of Sainz, Russell, Stroll and Perez in a session that was red-flagged early on when Leclerc span off and was unable to get going again.
With only a handful of laps completed, the Monegasque goes into the Shootout blind, other than for the data acquired by his teammate.
McLaren has brought a raft (10) of updates all of which are only available to Norris. However, the Briton was unhappy with his car and finished well down the order, while his teammate, who has only "half" of the updates, was quickest until being eclipsed by Verstappen.
A number of teams appeared to split strategies, while many drivers found the softs to be less grippy than the mediums, some feeling they weren't even good enough for a full lap.
Alonso only ran the hards, but teammate Stroll ran the softs and finished fifth.
The lights go green and Leclerc, followed by Zhou, Bottas, Stroll, Alonso, Sainz and Norris.

While most drivers pit, a few stay out to try their luck again.
"If that's not a penalty, I don't know what is," says Piastri of Bottas, who had clearly not been warned that the McLaren was closing.
"That was a close call, pretty dangerous," says Zak Brown. "It's really the team's responsibility to let the drivers know what is going on around them, so I'd be surprised if there isn't some kind of penalty."

"I hit the wall," reports Hamilton, as teammate Russell fails to improve on eleventh.
Both Mercedes out... and Toto Wolff is clearly unimpressed.
"I've got nothing, man," says Hamilton.
Norris is quickest, ahead of Perez, Leclerc, Verstappen, Ricciardo, Piastri, Alonso, Sainz, Stroll and Hulkenberg.
We lose Russell, Hamilton, Ocon, Magnussen and Tsunoda, the RB driver, like Verstappen, only given the one lap in which to make his mark.
The lights go green for S3 but there is no rush to action, indeed when the first driver breaks the deadlock - Hulkenberg - there is only 3:40 remaining.

Told he's got pole, Verstappen asks: "What happened to the others?" Indeed, Max, indeed.
On-board footage shows Norris really struggling for grip.
"To be honest with you, it felt pretty terrible," says Verstappen despite taking pole. "Maybe that last session, it was just really difficult to get the tyres to work. I didn't improve much on the soft but I'll take it.
"It didn't feel enjoyable to drive," he adds, "practice was really comfortable, I was quite confident we could fight for pole. But qualifying it didn't look like that for me... I don't know what happened to the other cars on that last lap."
