EJ Obiena wrapped up his first Olympic campaign as he crashed out of medal contention in the men's pole vault finals following three unsuccessful attempts at 5.80m.
Obiena, the only Asian in the final, almost cleared 5.80m on his first and second attempts but knocked the bar off on both occasions.
Initially ruled eliminated after hesitating twice on his third attempt, Obiena was given another shot to advance after a lengthy talk with the officials.
However, it was just not meant to be for Obiena, whose personal best stands at 5.87m, as he failed to clear 5.80m on his official third attempt.
Nesthy Petecio fell short of becoming the Philippines' first Olympic boxing gold medalist after settling for silver in the women's featherweight class following a unanimous decision loss to Sena Irie of Japan in the finals.
It was a heartbreaking loss for Petecio as she fell victim to Irie for the third time in their four encounters.
All five judges scored the bout in favor of the hometown bet, 30-27, 29-28, 29-28, 29-28, 29-28.
Still, Petecio made history as the first Filipina to win an Olympic boxing medal as she matched the silver won by Mansueto "Onyok" Velasco in the 1996 Atlanta Games.
Carlo Paalam pulled off a major upset over reigning Olympic champion Shakhobidin Zoirov of Uzbekistan as he punched his ticket to the men's flyweight semifinals, securing at least another bronze for the Philippines.
Paalam won via split decision in a shortened bout, with the referee stopping the duel in the second round after a clash of heads opened a cut above the left eye of Zoirov.
The Filipino earned the nod of four judges with identical scores of 20-18 to become the Philippines' fourth medalist in Tokyo.
One judge had it tied at 19-19.
In potentially one of the biggest days for the country in the Tokyo Olympics, three Filipinos are in prime position to add to the Philippines' medal haul on Tuesday, August 3.
