Consolation for Georgia in Sheffield.
After qualifying second fastest in the heats, Davies missed the 100m backstroke final on Tuesday night as the Welsh law student failed to report to the pre-race call room in time, saying she was 30 seconds too late on her Twitter site.
Lizzie Simmonds went on to be a clear winner in the 100m backstroke final to qualify for the World Championships in Shanghai in July alongside Gemma Spofforth.
But Davies showed her resilience last night by responding in style over the shorter distance and posting the third fastest 50m backstroke in the world this year of 27.96secs and just 0.04 secs outside the British record.
It was a personal best and a Welsh record as Davies swam inside 28 seconds for the first time in her career.
But because the 50m backstroke is not an Olympic event British swimming have decided not to send anyone to the World Championships in China, which is very harsh on Davies.
Davies has been unable to join Swansea stablemates Jazz Carlin, Jemma Lowe and Tom Allen on the Great Britain squad, while David Davies yesterday pulled out of China because of fatigue.
Welsh swimmer Marco Loughran failed to join his Commonwealth Games team-mates as he lost out to Chris Walker-Hebborn, who booked his place for this summer's World Championships with a season's best 1.57.20 in the 200m backstroke, with Cardiff's Xavier Mohammed finishing in sixth.
Walker-Hebborn recorded the sixth fastest time of the year and will join James Goddard on the plane.
