Jessica Hardy won the 50 metres freestyle at the US Olympic swimming trials in Nebraska on Monday as Dara Torres was denied in her bid to make a sixth Olympic team.

Torres, 45, finished fourth in the final behind Hardy, Kara Lynn Joyce and Christine Magnuson.

Hardy clocked 24.50sec to add the 50m to her surprising 100m free triumph with Joyce second in 24.73.

In the only other event on the final night of the Olympic trials, Andrew Gemmell won the 1,500m freestyle in 14:52.12 with Connor Jaeger nabbing the second ticket to London in 14:52.51.

Torres was trying for just one and when the effort was done she said her swimming career was over.

“This is really over,” Torres said.

Torres lingered at the finish, hugging Hardy and Joyce in the lanes to either side of her and taking a long look around as she exited the pool.

“That’s it. I’m going to enjoy some time with my daughter, have a nice summer and cheer the US team at the Olympic Games.”

Torres had already become the oldest woman swimmer to compete in the Games when she won three silver medals in Beijing at 41.

Since then she has undergone reconstructive surgery on her left knee, and coped with the death of German-born coach Michael Lohberg, who helped guide her to a fifth Olympics eight years after her fourth.
