Ginny Fuchs was the second U.S. fighter to suffer a loss on Thursday and the fourth overall to be eliminated from Olympic competition. Her journey ends with a three-round unanimous decision loss to Bulgaria's Stoyka Krasteva.

Scores were 30-27, 30-27, 30-27, 29-28 and 29-28 in favor of Krasteva, who beat Fuchs in a separate tournament just five months ago. Full story on their Round of 16 matchup can be found here: boxingscene.com/ginny-fuchs-drops-decision-stoyka-krasteva-eliminated-from-tokyo-olympics--159471

Krasteva will next face number-two flyweight Yuan Chang (China), who outclassed Great Britain's Charley Davison over three rounds of action. 

Scores were 29-28 on four scorecards and 30-27 on the fifth, all in favor of Chang who has emerged as one of the most established female fighters to ever come out of China. She was impressive the entire way through her battle with Davison, a mother of three who has enjoyed a terrific comeback since returning to the sport in 2018 following a seven-year exit.

Ingrit Valencia moves within one win of claiming her second consecutive Olympic medal. It came at the expense of a legend being eliminated from competition, as Valencia outpointed 2012 Olympic Bronze medalist Mary Kom in their Round of 16 bout Thursday afternoon at Kokugikan Arena in Tokyo. 

The tone was set from the opening bell, as Valencia raced across the ring while Kom was finishing up a quick pre-fight ritual. The battle of southpaws jumped off from there, with Kom throwing the heavier shots but Valencia—the number-three seed at flyweight—connecting with the cleaner blows during most exchanges. 

Kom's workrate was enough to win round two on three scorecards. Valencia was still beating the Indian boxer to the punch, shooting her jab and landing an occasional straight left hand. Valencia was the far busier and more accurate of the two in the third and final round, which is seemingly the last of Kom's incredible career. 

Valencia will advance to the quarterfinal round, the third member of the Colombian team to advance that far in Tokyo. She will face the house fighter in Tsukimi Namiki (Japan), who scored a decision over Graziele Sousa (Brazil).

Scores were 30-27, 30-27, 30-27, 29-28 and 29-28 in favor of Namiki, who jumped out to a strong start. The Japanese flyweight continued at an aggressive pace, even as she was well ahead going into the final round. 

Philippines was dealt its first loss of this year's Olympic competition while Thailand remains perfect, as Irish Magno (Philippines) fell short in her Round of 16 women's flyweight battle with Jutamas Jitpong (Thailand). Scores were 30-27 on four cards and 29-28 on the last in favor of Jitpong in an entertaining but one-sided affair.

Jitpong offered a disciplined performance, using constant lateral movement and never allowing Magno to dictate the pace. It went a long way in winning over the judges, as Jitpong only lost one round out of a combined 15 across the five cards. 

A tougher task awaits Jitpong in the quarterfinals, where she faces the division's number one seed.

It nearly didn't come to that, as top-rated Buse Naz Cakiroglu (Turkey) barely survived her first bout of Tokyo competition, claiming a split decision win over Tursunoy Rakhimova (Uzbekistan) in their Round of 16 pairing.

Scores were 29-28 on all five scorecards, three for Cakiroglu and two for Rakhimova in a fight which was THAT close. It was also tough to watch, as it featured more takedowns and grappling than there was actual clean boxing. 

Rakhimova jumped out to an early lead, landing the more telling punches on the occasions she wasn't being thrown to the canvas. Cakiroglu pulled even after two rounds on every card she previously trailed and managed to win round three on four of the five cards, although from which there was little to choose.

Nina Radovanovic remains a one-woman wrecking machine. The lone Olympic representative for Serbia has yet to lose on any judge's scorecard, including her unanimous decision win over Ornella Havyarimana (Burundi).

Scores were 30-27, 30-27, 30-27, 30-27 and 30-26 in favor of Radovanovic, who had no issue with eating one punch to land several. Havyarimana would land an occasional stiff right hand, though often met with combination punching and body shots from Radovanovic who improved on her win over Canada's Mandy Bujold on Sunday to advance to the quarterfinals.

Next up for Radovanovic is Hsiao-wen Huang (Chinese Taipei), the division's number-four seed who outboxed Giordana Sorrentino (Italy) en route to a unanimous decision. 

Scores were 30-27, 30-27, 30-27, 29-28 and 29-28 in favor of Huang, who put her height advantage to good use. Huang worked her long jab and fended off the stocky and scrappy Sorrentino long enough to remain alive in Olympic competition.

All women's flyweight quarterfinal bouts take place Sunday afternoon.
