IRELAND’S SIOFRA CLÉIRIGH-Buttner failed to qualify for the semi-finals of the women’s 800m at the IAAF World Championships.
The 21-year-old was the only Irish athlete in action on Thursday evening as she made her world championship debut at London’s Olympic Stadium.
She kept pace with the leaders through her first 400m but faded on her second lap as America’s Charlene Lipsey won the heat in a time 2:02.74.
Cléirigh-Buttner ran 2:06.54 to finish sixth, more than four seconds slower than her season’s best time.
Rio silver medallist Francine Niyonsaba of Burundi was the fastest qualifier overall (1:59.86), while reigning Olympic champion Caster Semenya of South Africa also comfortably won her heat (2:01.33).
