Ireland's Oliver Dingley missed out on qualification for the semi-finals of the 3m springboard at Tokyo 2020.

The two-time Olympian, who became the first Irish diver to compete at the Games in 68 years at Rio 2016 where he also reached the final, required a top 18 finish to advance from Monday's preliminary heats.

But the 28-year-old finished up 25th overall of the 29 participants with an overall score of 335.00 after his six dives at the Tokyo Aquatics Centre.

Chinese duo Zongyuan Wang and Siyi Xie set the two top overall scores of 531.30 and 520.90 respectively.

Dingley's opening dive was 3.0 difficulty and left him ranked 22nd overall with a score of 63.00, before his second effort dropped him back to 27th.

His third dive, with a degree difficulty of 3.4, saw him move up to 26th but his 3.0 difficulty fourth dive saw him move back down to 27th overall.

Dingley's sixth and final effort with a 3.4 degree of difficulty ultimately saw him finish 25th overall but not enough to qualify for the next stage of the competition.

"It was one of those things, I've experienced the highs and the lows of the Olympic Games. I feel a bit useless after that one but at the same time, it's been five years, I feel very proud to be able to stand up on that diving board and represent the country," he told RTÉ Sport after the preliminary round.

"It's hard to take and in a sport like diving where the smallest of mistakes in the air costs you. It really emphasises the mistakes especially, so it's like a bit of a chain reaction."

Emphasising that he still carries the positive memory of making the final in Rio five years ago, he added: "The last dive I tried to take it all in a little bit more and put a bit of a smile on my face."

Dingley said that his thoughts are now turning to supporting team-mate Tanya Watson who will compete in the women's 10m springboard preliminary round on Wednesday.

"She's a phenomenal talent and looking forward to seeing her doing her thing and it'll be nice to be in the stands cheering her on."
