Britain's Dina Asher-Smith finished third in the 200m at the Rome Diamond League as Jamaica's Shericka Jackson won ahead of Elaine Thompson-Herah.

Asher-Smith, who will defend her world title in the United States next month, was close behind in 22.27 - her best time this season.

American Allyson Felix, in her final season before retirement, was seventh.

Bahamian Shaunae Miller-Uibo was fourth in a field stacked with Olympic champions, with Britain's Beth Dobbin ninth in 23.36 at the Stadio Olimpico.

Asher-Smith told BBC Sport she was "quite happy" with her performance, adding: "I was hoping for maybe a bit of a quicker time but it was quite a good run.

"It was a really good field so I finished very highly in that. You always want to go out and win but sometimes it's about the journey and you have to have your eye on the championships."

In the 1500m, Olympic silver medallist Laura Muir, continuing her return from a back injury, finished third in four minutes 4.93 seconds.

Muir kept pace with winner Hirut Meshesha and Axumawit Embaye, who finished second, but did not have the speed to overtake the Ethiopians on the final straight as they crossed the line in 4:03.79 and 4:04.53 respectively.

In the pole vault, Team GB Olympic bronze medallist Holly Bradshaw, who missed the 2022 indoor season, was joint-second with a season's best jump of 4.60m as American Sandi Morris won with 4.81m.

Briton Lina Nielsen finished fourth in the 400m hurdles in a personal-best 54.73 seconds, while Lawrence Okoye was fifth in the discus with 64.72m.

Jemma Reekie's 2:00.28 was enough for ninth in an 800m race won by American Olympic champion Athing Mu in 1:57.01 - a world-leading time this season.

Jazmin Sawyers was seventh in the long jump with 6.61m as Ukraine's Maryna Bekh-Romanchuk won with 6.85m.

In a non-Diamond League event at the same stadium, Nethaneel Mitchell-Blake came fifth in a season's-best 20.59 seconds as American Kenneth Bednarek won in 20.01, also his best of the season.

Jacobs confident despite injury

The sixth meeting of the season takes place in Oslo on 16 June, with two others after that leading up to the World Championships, which begin in Eugene on 14 July.

Italian Olympic 100m champion Marcell Jacobs attended the Rome meeting but was unable to race because of a hamstring injury.

Having won 60m gold at the World Indoor Championships in March, Jacobs hopes to return in time to add a world 100m title to the shock gold he won in Tokyo.

"I know we can do really well in the World Championships," he told BBC Sport.

"Of course [I am confident]. My head is really strong. It is not the first time I've had an injury but I'm really determined and concentrated on this World Championship."

Jacobs said he would have to run faster than the personal best of 9.80 seconds achieved in Tokyo to win in Eugene, and when asked if he could do this so soon after an injury he replied: "I can."
