乒乓球澳門世界杯激戰正酣，北京時間4月18日，女單首個四強出爐，兩位日本選手狹路相逢展開內戰，結果奧運冠軍伊藤美誠（世界排名第九）惡戰6局后4-2險勝隊友大藤沙月（世界排名第八）晉級，由此而繼2020年之後再次奪得世界杯單打獎牌，詳情請看下文。

Ito Misei was once a well-deserved sister of Japanese women's table tennis, and she was also the number one opponent of the national table tennis women's team, not one of them, during the Tokyo Olympics, she slashed a gold (mixed doubles) a silver (women's team) and a bronze (women's team), but as a result, she began to decline as soon as she reached the peak, and later failed to be selected for the Paris Olympics.

至於大藤沙月則是去年急速崛起的日本小將，年初還沒有世界排名，年中就已經躋身前十，目前在第八的位置、高於伊藤美誠（第九），而且最近還兩連勝對方，此戰伊藤美誠凶多吉少。

After the start of the match, Ito Misei fell behind at the beginning and was sent two service errors by the opponent in a row, and then Satsuki Oto's mentality was obviously affected, and the result was quickly reversed, and finally Ito won the first game 11-0. However, in the second game, Satsuki Oto did not make any more low-level mistakes, and Ito was immediately broken by the opponent's spin and then lost 0-0.

In the third game, Ito won with a key ball and won 11-0 to take the lead again, but in the fourth game, he was quickly defeated by the opponent and lost 0-0, and the two returned to the same running line again.

The fifth game was very dramatic, Satsuki Oto started behind to achieve a comeback, but as a result, he was overturned with 7 game points, and finally Ito won 0-0, just one step away from victory. In the sixth game, Satsuki Oto fell into passivity again, and was finally ended 0-0 by Misei Ito, which stopped the women's singles quarterfinals and missed the medal.

From a technical point of view, Satsuki Oto, who plays the two-sided anti-rubber arc ball, is definitely more comprehensive than Misei Ito, who has one side of the anti-rubber and one side of the raw rubber, but the experience of the competition is obviously not as good as the other party, so he still looks a little flustered on the court, and it is a pity to lose in the end.
