The visiting Pinay footballers, ranked 57th in the world, started the scoring in the first half in the 45th minute through Carleigh Frille.
The Filipinos took a 1-0 lead against the 37th-ranked Costa Rica team in the first half.
However, in the second half, the team failed to continue with their momentum and allowed the host team to score two goals, leading to their defeat.
Despite the defeat, the team remains happy with their performance in their two-game friendlies.
In their first meeting last October 8, the game ended in a 1-1 draw.
A last-second goal by Katrina Guillou saved the Philippines from defeat in their game.
After the Costa Ricans' unsuccessful attempt to clear their lines from a set-piece, the 28-year-old midfielder poked the ball home in the 90+3 minute.
Coach Alen Stajcic's team overcame a one-goal deficit thanks to forward Priscilla Chinchilla of Costa Rica, who scored in the 57th minute off a pass from her captain, Melissa Herrera.
Before that, the first half of play between the two teams ended in a scoreless draw.
Goalkeeper Olivia McDaniel was kept busy the entire quarter as she made some excellent saves to stop players like Cristin Ganados and Carolina Venegas.
The Filipinas, on the other hand, hardly ever bothered Tapia. Carleigh Frilles, a forward, nearly scored, but her shot exceeded the bar.(Romeo Braceros Jr.)
