NATIONAL record holder Nickisha Pryce is to make her professional debut at Saturday’s Diamond League meet at Olympic Stadium in London, England.

The meet is the final major dress rehearsal for the fast-approaching start of the Olympic Games in Paris, France.

The 23-year-old Pryce, who ran 48.89 seconds to win the NCAA Division One championships in June and retained her Jamaican championships title, is ranked number two in the world. She will be defending an eight-race unbeaten streak.

Pryce, the former Vere Technical, Iowa Western, and University of Arkansas standout, is one of nine Jamaicans down to compete in the 10th stop on the season-long Diamond League circuit.

Pryce is to face a tough field which includes her Arkansas teammate Amber Anning, Poland’s Natalia Kaczmarek, and Lieke Klaver of the Netherlands — all of whom have run under 50 seconds this season.

Meanwhile the two 400m hurdles races are expected to be competitive, with three Jamaicans — led by world number three-ranked Rushell Clayton as well as Shiann Salmon and Andrenette Knight — set to feature.

Olympic Games medal favourite Femke Bol of the Netherlands is heavily tipped to win while American Shamier Little is expected to feature prominently.

World Championships finalist and national record holder Roshawn Clarke is to make his first competitive appearance since the national championships during which he lost to Malik James-King.

Clarke faces a quality field led by Brazil’s Alison dos Santos and also comprising Kyron McMaster of the British Virgin Islands, American CJ Allen, and France’s Wilfried Happio.

Ackeem Blake and Yohan Blake could be made to work hard in the men’s 100m race in which world champion Noah Lyles will race for the first time since he won the United States Championships in late June. The American, world number four-ranked runner will hope to make a statement going into the Olympics.

Botswana’s Letsile Tebogo, South Africa’s Akani Simbini, and the British pair of Louie Hinchcliffe and Zharnel Hughes will ensure a fast race. Hughes is returning from an injury layoff.

Many-time national champion Natoya Goule-Toppin is down for the women’s 800m and goes up against two quality British runners, Keely Hodgkinson and Jemma Reekie. The field is to also include Uganda’s Halimah Nakaayi and American Allie Wilson.

Zandrion Barnes is to contest the men’s 400m race that is to feature Canada’s Christopher Morales-Williams taking on Great Britain’s Matthew Hudson-Smith, Bayapo Ndori of Botswana, Trinidad’s Jereem Richards, and American Vernon Norwood.
