Noah Lyles, edged into third place over 100 metres by his United States compatriots Christian Coleman and Ronnie Baker in Rabat last week, remains unbeaten in the Diamond League over 200m, and will continue his defence of the title he won in Brussels last year against a field that includes Turkey’s world champion Ramil Guliyev.

Lyles has won Diamond League victories in Doha, Eugene and Lausanne so far this season, running a personal best of 19.69sec in the first and last of those three, the fastest recorded so far this season.

The charismatic young sprinter from Gainesville, Florida, who turned 21 yesterday, beat Guliyev in Doha and Eugene, although the Turk took full advantage of his absence in the Oslo and Stockholm Diamond League legs to earn maximum points.

Elsewhere, the women's 400m will see the first Diamond League meeting of The Bahamas' Olympic champion Shaunae Miller-Uibo, who won in Eugene in 49.52, the fastest time so far this season, and the 20-year-old Bahrain runner Salwa Eid Naser.

The latter has won the last four Diamond League meetings in Oslo, Stockholm, Paris - where she set an Asian record of 49.55 - and Lausanne.

Miller-Uibo warmed up for this race by winning over 200m in 20.29 at the meeting in Rabat.

The final event on the programme, the men's 3,000m steeplechase, will be in large part a re-run of the competitive race in Rabat, where Kenya's Benjamin Kigen won in a personal best of 8min 6.19sec, the fastest run this year, from Ethiopia's Chala Beyo, who set a personal best of 8:07.27, and Morocco's world silver medallist Soufiane El Bakkali who ran 8:09.58.

All three are in the field, along with the world, Olympic and Commonwealth champion Conseslus Kipruto - a winner at the non-Diamond League race in Rome on May 31 in 8:08.40 but only 12th in Morocco in 8:27.36.

Evan Jager, the US world bronze medallist and Rio 2016 silver medallist, and France’s Rio 2016 bronze medallist Mahiedine Mekhissi Benabbad have also joined the party so everything points to a great race.

South Africa's world and Olympic 800m champion Caster Semenya, who has explored her potential over longer distances in the last couple of weeks, returns to her main event and will be seeking to better the extraordinary personal best of 1:54.25 she set at the Paris Diamond League meeting on June 30.

Semenya, who finished sixth in the Lausanne 1,500m in 4:00.44 and then set the fastest 1,000m seen so far this season, 2:31.01, in Rabat, will face Burundi's world and Olympic silver medallist Francine Niyonsaba, who won in the South African's absence in Lausanne on July 5.

Also in the field are the world bronze medallist from the US, Ajee Wilson, and Rio 2016 bronze medallist Margaret Wambui of Kenya.

Russia's world 110m hurdles silver medallist Sergey Shubenkov, competing as an Authorised Neutral Athlete, will expect to dominate the field once again having run three sub-13sec races this month, lowering his personal best to 12.92 in the process.

Kenya's Elijah Manangoi may have beaten his training partner Timothy Cheruyiot to the world 1,500m title last year but this season it has been the latter athlete who is preeminent. 

Cheruyiot remains unbeaten over his strongest distance this season, and has twice beaten Manangoi, at the Eugene and Rome Diamond League meetings. 

The two meet again in Monaco in a stellar field that also includes the Rio 2016 champion Matt Centrowitz of the US and Ayanleh Souleman of Djibouti.
