Femke Bol must have used up her tank in the 4x400 mixed cuz she looked really off and had nothing at the end of the race.
Which is funny to say since she still placed 3rd... but she ran a 52.xx something and Bol had run a 50.95 last month.
Of course that 50.95 was still almost 1/3 of a second slower than Sydney's US time trial time (which broke her own WR).
Only way Bol wins the match-up is if Sydney had an 'off-night' and Bol was at her best. Well Sydney was at her best and Bol had the off-night.
