English falls short
Mark English turned in another superb effort last night when he was just beaten by Poland's Adam Kszczot in a 600-metre contest at the Golden Spike meeting in Ostrava.
The race was billed as a world record attempt by Olympic champion David Rudisha but he pulled up injured after just 100 metres.
English, meanwhile, looked as if he would triumph for much of the contest but he was overtaken close home by Kszczot, though the Donegal man did have the consolation of notching an Irish record of one minute, 16.14 seconds.
Usain Bolt won the 200 metres in his season's best time of 20.13 seconds in rainy, cold conditions.
His Jamaican compatriot Asafa Powell claimed the 100m in 10.04 seconds but failed to match his season's best of 9.84 and the world leading 9.74 set by Justin Gatlin on May 15 in Doha.
Isiah Young of the United States finished second in both races, trailing home behind Bolt in 20.35 and Powell in 10.13. American Dedric Dukes has the world leading 200m time of 19.99.
