Kat Driscoll finished in fourth place in the trampoline final at the London Prepares gymnastics test event at the North Greenwich arena.

Britain have already booked themselves a women’s trampolining place at the Olympics at last November’s World Championships after Driscoll made it into the individual final.

However, the trampolinist who will take that place is yet to be decided, with Driscoll using this event to boost her chances of securing the spot for herself.

The gymnast from Kent was second-last to perform in qualifying and she booked her place in the final after a compulsory routine of 46.710 and a solid voluntary performance of 54.390 saw her finish third.

In the final, Driscoll produced another strong routine, meaning she now has two Olympic qualifying scores to her name.

The British champion scored 53.730 but missed out on a place on the podium as she finished fourth behind Canada’s Rosannagh MacLennan who won gold, Holland’s Andrea Lenders in silver and Ana Rente of Portugal who took bronze.

It was a bad day for reigning Olympic champion He Wenna and team-mate Li Dan of China, as Li missed out on the final after a poor voluntary routine, and He – who qualified with the highest score – needed to be caught by the spotters as she came off the trampoline.

Driscoll is the only member of the GB women’s team so far to have recorded the results needed to secure the Olympic berth and believes the experience of competing at the test event has given her an extra advantage.

“I wouldn’t say I can take it easy now but there’s not as much pressure on my shoulders,” Driscoll said.

“I’ve got two preliminary scores which I need and two final scores, which I need.

“It does take a little pressure off going to the European Championships as I can work on refining what I’m doing while the other girls need to get scores on the board.

“It’s important that if I come back here in the summer I know what it feels like, I know what it looks like and it’s important for me that I’ve had that experience it’s not going to be unfamiliar when I come in.

“That was the biggest help I could have had and especially to come out in prelims and score what I scored it’s a big thing to take away and a big confidence boost.”

In the final of the men’s event, China’s double world champion Dong Dong claimed gold ahead of team-mate Lu Chunlong in a reversal of last November’s World Championships, with Japan’s Masaki Ito taking bronze.
