DIAMOND DEBATE: A hot 100m hurdles

Raymond Graham: Wow. What a line-up we have for this women's 100m hurdles in Monaco with a few weeks to go to the World Championships in London! The top medal contenders are all here in what will be one of the most exciting races this season.

Andre Lowe: I'm most excited to see what the defending world champion, Danielle Williams, can do in this race. For some strange reason, we haven't seen a lot of her against the world's best on the circuit, but she will get her chance tomorrow.

Raymond Graham: Indeed. Her performance here against these heavyweights will surely give an indication of what to expect at the World Championships, and she does love high quality competition.

Andre Lowe: "Even without regular head-to- heads with her rivals, Williams has gone 12.56 seconds this season with only five women going faster this year. All five of them are in this race with world leader, world record holder and gold medal favourite in London Kendra Harrison leading an extremely talented line-up."

Raymond Graham: Harrison is the big favourite, of course, but if she gets early pressure, she could be in trouble as in her last race, the veteran Sally Pearson of Australia, who is rounding into good form, was right up there with her for majority of the race, and another run like this from the Australian could cause the American to panic, as she is normally fast away out of the blocks from her rivals."

Andre Lowe: She has dealt with pressure well. I'm not betting against her. It's people like Jasmin Stowers who tend to struggle under pressure - by the way, I don't think she will finish in the top three here for instance. Williams has a good chance to test Harrison especially with her better speed between hurdles. She will finish in the top three for sure but in the end I think Harrison's smooth hurdling will give her the advantage in what I expect will be a close race."

Raymond Graham: Despite her woes this season, I am not turning from Stowers, and I am giving her another chance to get it right. I am confident she will finish in the top three. Harrison will score another win, but it will be tight for the next two spots, and I am siding with Stowers over Pearson here.

Andre Lowe: Harrison, Pearson and Williams will take the top three spots here, no doubt!
