Philippines Women might have lost the match. But they can definitely hold their heads high. Singapore is an ICC member since 1974, and they were one of the founding members of the Asian Cricket Council (ACC). On the other hand, Philippines got their ICC membership in 2003. But compare both these teams. Most of the Singapore players are expats from India, England or Australia, while Philippines has a mostly native squad. And this points to a brighter future for the Philippines team in the long term.
This may be the only reason for the loss, but not because there are many records that show that even after entering the new cricket arena, they have achieved victories over other old giant teams. It's all depends on their player and their form.
Anyway, I also seeing that there is not much gap between the Singapore and the Philippines in the ICC cricket ranking. Where the Singapore is on 65th rank and on the others hand there Philippines was in only 69. Anyway, I not saying that Philippines is stronger team than Singapore team but we can not predict just on those facts
