Malaysia's run at the BWF World Tour Finals in Bali ended in the semi-finals as Lee Zii Jia, Chan Peng Soon-Goh Liu Ying and Ong Yew Sin-Teo Ee Yi all lost on Saturday.

Their defeats were painful as all of it came in straight games, with fans hoping in anticipation to see at least one representative in the final.

Chan-Goh were first to be sent packing 8-21, 18-21 by Dechapol Puavaranukroh-Sapsiree Taerattanachai in 42 minutes.

The experienced pair had started this tournament well with two consecutive wins, but lost the next two in tame fashion.

Ong-Teo hould also be upset with their 18-21, 15-21 loss to Takuro Hoki-Yugo Kobayashi in 39 minutes.

Like Chan-Goh, the pair won their first two matches but faltered in the next two.

The Malaysians had also lost to Hoki-Kobayashi in their final group match, but fared better in that loss by taking the contest to a decider.

Of the lot, Lee came into his match-up against Kunvalut Vitidsarn as the biggest bet to make the final, having beat his Thai opponent in straight games in the group stage.

But the three-time world junior champion avenged his loss to the Malaysian in sweet fashion, winning in straight games 21-18, 21-18 in 44 minutes.

Lee was having a torrid day at the office, with his game littered by numerous unforced errors that paved the victorious path for Kunvalut.

Kunvalut either plays Viktor Axelsen or Lakshya Sen in the final.

The women's doubles final on Sunday sees South Korea's Kim Soyeong-Kong Hee-yong face Japan's Nami Matsuyama-Chiharu Shida.

In the mixed doubles, Yuta Watanabe-Arisa Higashino have a date against Dechapol-Sapsiree, while An Seyoung takes on P.V.Sindhu in the women's singles final.
