When you get to the final of the 60m there'll be false starts and people going out you don't expect to, and there are just hundredths of a second in it.
No one has been winning under 6.50 seconds so the winning time may well be 6.53, which Williamson is capable of.
It's a big test for him after what's happened with selection, but he's 22 and I'd like to see him doing well.
This may help him push into the summer. It's a huge opportunity and hopefully he can grab it.
