Earlier, Sarah Lavin broke Derval O'Rourke's 13-year-old Irish 100m hurdles record but it wasn't enough to secure a place in the World Championships final.
The Limerick athlete clocked 12.62 seconds to cut 0.03 off O'Rourke's mark as she was fifth in her semi-final.
US star Kendra Harrison (12.33) and Bahamian Devynne Charlton (12.49) were the automatic qualifiers from Lavin's heat.
Switzerland's Ditaji Kambundji (12.50), who clinched one of the two fastest losers spots, and Jamaica's Megan Tapper (12.55) were in third and fourth spots.
Lavin, who cut 0.05 off her previous personal best set earlier this month, has produced the season of her life despite the huge tragedy of the death of her boyfriend World Rally Championship star Craig Breen who was killed in April after a crash during a testing session for the Croatia Rally.
The Limerick athlete went on to win a bronze medal at the European Games in Poland before continuing her brilliant form on the circuit.
O'Rourke, who won the 60m hurdles world indoor title in 2006, set her Irish 100m hurdles record when taking the silver medal at the European Championships in Barcelona in 2010.
