At this stage of things it becomes a psychological thing. Jeremiah Azu is getting quicker and quicker, but can you deliver your best under pressure?
He will go into the final now as one of the favourites.

Ireland's Kate O'Connor jumped a personal best of 6.32m in the long jump to finish third in that discipline.
She now has 949 points and that puts her in the bronze medal position going into the final discipline - the 800m - which takes place later on.
She won that event at the European Indoors a few weeks ago. Can she maintain that medal spot at the Worlds?

British team captain Neil Gourley speaking on BBC Two after qualifying for Sunday's men's 1500m final: "It was exactly how I planned it. I just let people do what they wanted early doors but I knew when I moved I had to make it stick. When I hit the front that had to be it.
"You're never actually sure, particularly if the crowd gets into it, where you are in relation to others, but I turned around and I could keep it controlled to the line.
"I gave a little speech earlier in the week [to the team] - I think I was a bit more nervous for that than this. I have enjoyed that, it's a small team but we're all close because of it."

To be able to make that move from as far back as he did, against that calibre of athlete... I think Jakob Ingebrigtsen's brother, Filip, said what he sees him do in training makes him scared to get out on the track and compete against him.
When he goes out and runs as confidently as that, you have to go back to the drawing board in terms of thinking about how you might compete with him.

And off we go in this second heat.
