Martin (hard-soft) responds to the early setback in style, going fastest at the halfway stage.
Only Pedro Acosta (3rd), Takaaki Nakagami (12th), Jack Miller (19th) and Augusto Fernandez (20th) are using the medium rear tyre.
Emilia Romagna winner Bastianini goes fastest with a 1m 30.582s. For comparison, his pace-setting Friday afternoon time attack was a 1m 29.630s.
Yamaha's Fabio Quartararo continues to impress, leading the early stages of the session on soft tyres, ahead of Enea Bastianini (hard-soft).
Crash for title leader Jorge Martin, who loses the front and falls at Turn 16.
The good news is that he's unharmed, keeps the bike running and gets it back to the Pramac pits.
Green flags are waved and final practice begins.
This is the last chance to work on race pace before this afternoon's Sprint.
As at Misano, the soft rear could well be the preferred choice for the Sprint, then the medium for the full-length race.
It's another hot and sunny morning as MotoGP prepares for the 30-minute final practice session at the Indonesian Grand Prix.
