World record holder Sophie Pascoe has qualified third fastest for tonight's S9 100m backstroke final.
Her heat was won by fastest qualifier, American Hannah Aspden who won bronze in Rio. Aspden was over two seconds outside Pascoe's record, set in 2019.
Pascoe, who has been reclassified to the S9 (more disabled), having swum S10 at previous Olympics, will face all of the medal winners from Rio in tonight's final, which starts at 8.21pm.
Spain's Nuria Soto easily beat Australian Ellie Cole in the other heat.
