If Ashish ended a disappointing 12th in the men's draw, then Dipa finished 10th in the women's section at the Namdong Gymnasium here.
Ashish, who won a bronze in men's floor exercise and later a silver medal in men's vault in 2010 Guanghzou Games, started off well in the floor exercise and fared better in the vault, but came a cropper in the remaining disciplines.
Japan's Yuva Kamoto won the gold and his teammate Masayoshi Yamamoto bagged the silver, while South Korea's Sangwook Lee stood third.
Ashish's accumulated score of 81.750 was way behind the total top score of Japan's Kamoto 87.950.
