Riza Pasuit's loss capped a winless day for the Philippines in the quarterfinals of the Asia/Oceania qualifiers in Amman, Jordan on Monday.
She fell to Wu Shih Yi of Chinese-Taipei in their lightweight match.
The taller Wu used her longer reach to prevent the compact Pasuit from inflicting damage.
Wu won via unanimous decision.
Out of 7 Filipino boxers, only Eumir Marcial, who made it through Sunday, joined pole-vaulter EJ Obiena and gymnast Carlos Yulo as the only Filipinos so far to reach the Japan Games.
Also on Monday night, Irish Magno lost to more experienced Mery Khom Hmangte of India.
Hmangte, a 6-time world champion, was the craftier fighter in their women's flyweight contest, frustrating Magno with her left straight-right hook on the way to a unanimous-decision win and a spot in the semifinals in Amman, to go with an Olympic berth.
Nesthy Petecio and Carlo Paalam also fell short in their Olympic bid.
Petecio, who came into the tournament as the top seed of the women’s featherweight class, got edged by Japan’s Irie Sena by split decision 3-2 in the quarterfinal round.
The judges saw it 30-26, 29-27, 29-27, 29-27 for Sena, while only one of them scored it 29-27 for Petecio, who expressed her disppointment on social media.
"Sorry po talo ako. Isang push na lang sana. Kung nasaktan po kayo at nanghihinayang isipin niyo po yung nararamdaman ko ngayon at yung panghihinayang. Higit pa sa break up, niloko at ginago ng jowa ung sakit po," she said on Facebook.
Paalam (men’s flyweight) also lost a tight decision to India's top-seed Amit Panghal 3-2.
They could still, however, catch the last bus to Tokyo via the Global Qualifiers in Paris in May.
