Diamond League: James Dasaolu fourth as Blake is injured

Britain's James Dasaolu equalled his season's best in the men's 100m Diamond League in Glasgow to boost his chances of European Championships selection.

Dasaolu, 25, clocked 10.03 seconds in Hampden Park in a race won by Jamaica's Nickel Ashmeade in 9.97secs, the quickest recorded in Scotland.

But double Olympic silver medallist Yohan Blake failed to finish the race.

The Jamaican, 25, pulled up injured and tumbled onto the track before leaving on a wheelchair.

Dasaolu, who is hoping British selectors award him the final 100m spot for August's European Championships, said: "I don't think it was the best of races but I've equalled my season's best in my second race of the season.

"I'm happy to run 10.03secs against some of the best in the world.

"It [selection] is not in my hands. I've done my running, whether or not I get selected I'm just going to enjoy the rest of my season and run a personal best, hopefully."

The Croydon Harrier, the second fastest Briton in history, is not certain of his place for Zurich as the sprinter, recovering from a hamstring injury, did not race at the British Championships in Birmingham, which doubled as trials for Switzerland.

Selectors will decide over the forthcoming days whether to give the third and final spot to Dasaolu or Chijindu Ujah - who has dipped under 10 seconds this season.

Dasaolu will not be returning to the revamped Hampden Park when the city hosts the Commonwealth Games later this month. He has has not been selected by England as he did not race during the selectors' qualifying period.

But heptathlete Katarina Johnson-Thompson will be competing again in Glasgow this summer and she said she had fallen in love with the stadium after leaping to a personal best 6.92m in the long jump.

In front of a 12,000 crowd, the 21-year-old's effort - just three centimetres short of Shara Proctor's British record - was good enough for second, behind American Tianna Bartoletta (6.98m) but ahead of compatriot Proctor (6.82m).

"I was facing a good field, and just tried to come out and grasp the opportunity before the Commonwealths," Johnson-Thompson, who is enjoying a remarkable season, told BBC Sport. "I love this stadium already."

Commonwealth silver medallist Will Sharman equalled his personal best in the men's 110m hurdles, beating a world-class line-up to win in 13.21sec.

Eilidh Child, 27, the leading European in her event this year, finished almost a second ahead of her nearest rival Cassandra Tate in the women's 400m hurdles, recording a season's best 54.39.

Puerto Rico's Javier Culson, 29, convincingly won the men's 400m hurdles in 48.37 seconds, with Olympic decathlon champion Ashton Eaton second in a personal best 48.69.

Welshman Rhys Williams achieved the 'A' qualifying time for Zurich, finishing fifth in 49.75 secs, while fellow Britons Niall Flannery (49.79) and Tom Burton (50.36) were seventh and eighth respectively.

British Champion Danny Talbot (20.44 secs) described the 200m line-up as the best field he had faced and was fifth in a race won by Alonso Edward, 24, of Panama in 20.25 seconds.

Laura Weightman achieved her highest-placed Diamond League finish in the women's 1500m. The 23-year-old British champion was fourth in 4:03.98, behind winner Sifan Hassan (4:00.67) of the Netherlands - who held off two-time world champion Abeba Aregawi (4:00.94).

In an exciting sprint finish in the men's 5,000m, world silver medallist Hagos Gebrhiwet (13.11.09) ran a 53.97 secs final lap to overtake his compatriot Yenew Alamirew (13:11.76).

US champion Francena McCorory (49.93 secs) powered down the home straight to push Olympic champion Sanya Richards-Ross (50.39 secs) into second in the women's 400m, in what was the first sub-50 second 400m run by a woman on Scottish soil.

Blake, who said he was not fit enough to compete at the Commonwealths, pulled up after 60m

The former world champion had only recently recovered from a succession of hamstring injuries
