Athletics: Dina Asher-Smith wins 100m at Diamond League in Birmingham - results as it happened

Dina Asher-Smith thrilled the home fans at the Birmingham Diamond League athletics meet at the Alexander Stadium on Saturday (21 May) after edging out Shericka Jackson to win the women's 100m.

Asher-Smith overcame the windy and relatively cool conditions to win in 11.11 seconds, telling BBC television after: "It's my first 100m of the season, it's a long season so we're easing our way into it. It's a very strong field. I could have done some things differently if we're being picky."

Her win was one of four British wins in the Diamond League events, alongside triumphs for Matt Hudson-Smith in the men's 400m, Laura Muir in the women's 1500m, and Keely Hodgkinson in the women's 800m.

Canadian Aaron Brown won the corresponding men's race. Meanwhile, women's long jump Olympic champion Malaika Mihambo again cleared 7m with her 7.09m setting a new meet record, while Hansle Parchment won the battle of the Jamaican hurdlers against Omar McLeod.

And Kristjan Ceh moved to 10th on the all-time men's discus throw after breaking the Diamond League record with a massive 71.27m.

And the last race of the day, another non-Diamond League relay, this time for the women.

It's a world lead time for the Brits – Beth Dobbin, Imani Lansiquot, Dina Asher-Smith, and Daryll Neita – in 42.29.

4:08pm – Canada win men's 4x100m relay

A non-Diamond League relay here.

Canada, anchored by Olympic 200m champion Andre de Grasse, come home as winners in 38.31.

Impressively, the French quartet in second appear to have broken the under-20 world record with their time of 38.41. That record is pending ratification.

3:53pm – Hodgkinson eases to 800m win

A popular win for the home crowd to celebrate to conclude today's Diamond League action.

Keely Hodgkinson comfortably wins the women's 800m in 1:58.64, pulling away from the field on the final straight.

The Olympic silver medallist makes it four wins for British runners today in Diamond League events after Hudson-Smith (M400), Asher-Smith (W100), and Muir (W1500).

3:47pm – Ceh wins men's discus

Kristjan Ceh is the only man of the Final 3 to get a valid mark, but doesn't improve on that mammoth 71.27 from earlier.

No matter – he wins in Birmingham and has all the new records to his name.

3:43pm – Parchment wins race between Jamaican Olympic champions

It's the hotly-awaited men's 110m hurdles, which sees the last two Olympic champions, Hansle Parchment and Omar McLeod of Jamaica, go up against each other.

McLeod starts well and is in the lead but Parchment overtakes him halfway through the race after McLeod knocks into a hurdle.

The pair embrace at the finish line.

A world-lead 13.09 for Parchment.

3:35pm – Diamond League Record – Kristjan Ceh in men's discus

Wow!

Slovenia's Kristjan Ceh has moved from 23rd all-time in men's discus to 10th on the all-time list after throwing a new Diamond League Record, national record, meet record, and world-leading 71.27 metres.

Olympic and world champion Daniel Ståhl is currently third.

3:33pm – Abel Kipsang wins 1500m from the front

Abel Kipsang is on a great run of form.

After winning in Doha last week, he's repeated it this week, winning a strong 1500m race from the front after the pacemaker dropped out.

The Kenyan clocks 3:35.15, ahead of Spain's Mohamed Katir.

3:27pm – Mihambo victorious in long jump

No improvements for any of the Final 3 in the last round of long jumps, although Malaika Mihambo did clear 7m again with a 7.06.

Her earlier 7.09 will stand as the new meet record and the winning mark today.

3:20pm – Seyaum impresses in 5000m

There's a lead group of five as the women's 5000m enters the last lap.

A strong kick by the Ethiopian trio around the final bend but it's Dawit Seyaum who clocks a big world-lead win.

14:47.55 takes more than two seconds off the world lead and some four seconds off the meet record previously held by the legendary Tirunesh Dibaba.

3:06pm – Morris takes pole vault victory

Sandi Morris, the world indoor champion and Rio 2016 silver medallist, takes the women's pole vault win in Birmingham.

She's the only woman to clear 4.73m, doing so on her final attempt to better her own world lead this year by one centimetre.

Tina Sutej and Katerina Stefanidi share second place on 4.65m – Tokyo Olympic champion Katie Nageotte could only manage 4.30m.

3:01pm – Malambo smashes meet record

Wow! This is big, big, big from Olympic champion Malaika Mihambo of Germany.

A huge world lead and meet record 7.09m on her fourth attempt.

That breaks her own mark of 6.96m set here in 2018.

2:58pm – Home win in 400m

The track races are coming thick and fast now.

The men's 400m is up next, including Botswana's Isaac Makwala.

But it's the Birmingham athlete Matthew Hudson-Smith of Great Britain, running on his home track, who takes the win with a late kick!

He comes home in 45.32 while there's a three-way photo-finish for second, third, and fourth.

American Bryce Deadmon is second in the end in 45.51.

2:50pm – Asher-Smith narrowly wins 100m

Asher-Smith time. Other names in this final include Gabrielle Thomas, the Olympic 200m bronze medallist, and Olympic finalist Aljja del Ponte.

Dina Asher-Smith starts very well and just holds off a charging Shericka Jackson of Jamaica.

11.11 the official winning time; 11.12 for Jackson and Britain's Daryll Neita is third.

"It's my first 100m of the season, it's a long season so we're easing our way into it. It's a very strong field. I could have done some things differently if we're being picky," a grinning Asher-Smith tells BBC TV.

2:41pm – Arop takes men's 800m

This is an 800m clinic from Marco Arop.

No-one follows the pacemaker's lead, and the group is together through the first 600m.

But Arop comes around the outside on the back straight on the last lap and kicks hard into the final turn.

The Canadian opens a huge gap and eases home to the win in 1:45.43.

2:38pm – Lovett beats Tamberi to high jump win

Another Canadian victory, this time in the men's high jump.

Django Lovett is the only man to clear 2.28m as he takes the win, beating Olympic champion Gianmarco Tamberi (2.25m) into second.

Poland's Norbert Kobielski, also at 2.25m, is third.

2:35pm – Aaron Brown wins men's 100m

After finishing second in the earlier men's 'B' 100m race, Canada's Aaron Brown clinches victory in the 'A' race.

They're off and running at the third time of asking and Brown in lane 8 starts very well and finishes strong to pip Jamaica's Yohan Blake.

10.13 the winning time. Jerome Blake of Canada is third.

2:34pm – False start!

A second false start in the men's 100m!

Zharnel Hughes is disqualified.

2:32pm – False start!

Time for the men's 'A' 100m, featuring Adam Gemili, Yohan Blake, Zharnel Hughes, Jerome Blake, Trayvon Brommell, Andre de Grasse, Reece Prescod, Aaron Brown, and Nathaneel Mitchell-Blake.

There's a false start, though – it's Brommell. That was very obvious – the American is disqualified.

2:20pm – Muir clinches 1500m

The home favourite and Olympic silver medallist Laura Muir, and Australia's Jessica Hull, are clear of the field with a lap to go in the women's 1500m.

Both women are nearly inseparable around the final bend before Muir kicks on the straight.

Muir wins in 4:02.82.

2:13pm – Allman confirms discus win

Allman and Perkovic both make the Final 3 of the discus.

Perkovic puts together her best throw on this sixth and last attempt for a 67.26, better than Allman's final throw of 65.23, but Allman wins thanks to her earlier 67.85 metres.

2:05pm – Muhammad takes hurdles win

The first of our Diamond League races is the women's 400m hurdles.

Dalilah Muhammad, the former world record holder and Rio 2016 Olympic champion, breezes to the win in 54.54.

The American opens up a comfortable lead on the finishing straight. Ukraine's Viktoriya Tkachuk and Anna Ryzhykova are second and third.

1:40pm – Allman into the lead

The reigning Olympic champion, Valerie Allman of the United States, is also in discus action.

The American has thrown 67.85 and is in the lead.

On the track, we're having a series of 'B' races. A number of British athletes are in these races, but a few big names – Gabrielle Thomas in the women's 100m and Aaron Brown in the men's 100m – are running both the 'B' and 'A' races, to replicate the feeling of a Championships event where they have to run both a semi-final and a final in the same night.

1:28pm – Action underway

The afternoon's Diamond League action is now officially underway with the women's discus, featuring the likes of double Olympic champion Sandra Perkovic of Croatia, and the men's high jump.

Perkovic has the early lead in the discus with a throw of 64.85m.
