"Doing well" relatively speaking, of course. If Ricciardo outscores teammate Yuki Tsunoda for the rest of the season, that is probably doing well enough to move up to Checco's seat.
“”Doing well” relatively speaking”
I think you are right and if Ricciardo finishes the rest of the season averaging around the tenth place would be an amazing seasom for him.
Even with that I don’t see Checco being replaced. He has had some weird things happen in qualifications but has run very well in the race.
