The entire TMZ Sports newsroom just became fans of Team Mexico ... because every time the squad scores a goal, Playboy's 2013 Playmate of the Year is celebrating by bouncing around in a skimpy top.
Raquel Pomplun -- who was raised in Tijuana -- is live-cheering the game with Playboy and Hornitos tequila ... which basically means she quickly records a sexy video anytime Mexico does anything noteworthy.
Earlier today, Mexico scored its first goal of the World Cup against Cameroon ... and Pomplun went wild.
Sooooo ... Viva Mexico!
