An international softball delegation will meet IOC president Jacques Rogge today, to try to win their reinstatement in the 2012 Olympics.
Softball and baseball were voted out of the Olympic program after 2008 this July.
Rogge has said the IOC could consider a re-vote, but only if the members ask for one.
Don Porter, International Softball Federation president, said:
"I am optimistic that this unified effort by our softball delegation will show Mr Rogge and the IOC members that almost three months after the vote, we remain committed to getting our sport back on the 2012 program".
