To think that this match was fixed is deplorable. It is was fixed, then Japan would have taken out its stars after the third set. They did not.
In volleyball the team that scores more points than their opponents wins the match 96.45% in FIVB, Olympics and Regional Championships (& Qualifiers) dating back 2002-2011.
Serbia outscored Japan yesterday.
The only way that this can be corrected would have been to play the Thailand-Peru and Japan-Serbia match at the same time in a different venue, but they only had one venue. Plus what happens if one match goes 3 sets, but the other goes 5. Someone will let the teams in the other venue know.
I am glad the FIVB made this statement, but I sincerely doubt that they will find anything because it did not happen.
