Unless something crazy happens I can't see it being anyone other than one of those 2. Neither Tim C or Nugese have looked great in rounds.
Jakob can't win if it doesn't go hard, which likely rules out someone like Hocker who has the best finish but probably won't be close enough. Then it is a question of which of Kerr or Jakob is in the best shape.
Shame for Lina there, she was on the verge of smashing her PB but obviously was at her limit. Again, like Charlie, potentially good for our relay chances even if disappointing for her!
