A misstep on the board in the last dive proved costly for Ahmad Amsyar Azman when he missed a place in the semifinal of the men's 3m springboard at the Rio Olympic Games here on Monday.

His sixth and final dive in the preliminary round saw him making a comical landing on the water, much to the amusement of the spectators and coaches alike at the Maria Lenk Aquactics Centre.

Ranked 12th after five dives and on course to be among the 18 qualifiers, Ahmad Amsyar's final dive brought laughter to the crowd and he received only 9.75 points.

All the others scored between 56 and 91 points in the last dive and his comical dive pulled down his ranking to the bottom with a total of 341.70 points.

China's Cao Yuan topped the list with 498.70 points.

"It was a tactical mistake on the board and I was off-balance before taking the plunge," said the heart-broken Ahmad Amsyar, who had taken the slot from Ooi Tze Liang for the Rio Olympics.

Tze Liang will compete in the 10m platform.

The 23-year-old diver admitted his mistake and said he did not know how it happened.

"Masih belum rezeki saya (My time has yet to come)," he said.

The semifinal has 18 divers and the top 12 will move into the final.
