The result is 26 centimeters shorter than Johansson's recent personal best, 19.54 – but still meant that she won the competition by far.
Johansson's shot was 80 centimetres longer than the runner-up in the competition, Jorinde van Klinken.
Johansson's series was even and good: 18.93, 19.08, 18.96, 18.94, 18.99 and with the last push she pulled off the best of the day.
