England's Fran Halsall set a new Commonwealth Games record earlier of 24.31 seconds in the 50m freestyle.
"I am quite surprised," she said. "Obviously after a late night last night I was keeping it all low key this morning and my coach told me just to get to 25m and switch off and just get through.
"I did that and felt quite good so it is quite a confident boost that I am in good form."
