Wot was going on?

What did the Japanese weather have in store for MotoGP? Nowt terrible. It was very racy at the start behind Bagnaia. Alex Marquez & Mir tangled and crashed out on lap 2/24. Acosta went from 2nd on lap 4.
    Martin and Marc Marquez worked their way up to 2nd and 3rd. Was that a rain flag with 15 laps to go? Viñales was gone with 13 laps left. Bastianini closed in on M. Marquez, who seemed to be having tyre trouble.
    Martin got close to the leader, Bagnaia, with 5 laps to go and the bikes casting shadows on the track. But the top 3 held their order to the finish line.
