The newly merged softball and baseball federation will meet senior IOC officials tomorrow to push their joint bid to regain Olympic status.
The new body, called the International Confederation of Softball and Baseball, is seeking a spot on the programme for the 2020 Games.
International Softball Federation President Don Porter says the meeting will help prepare a presentation to the IOC's programme commission on December 18-19.
Baseball federation president Riccardo Fraccari says further talks are planned with Major League Baseball about releasing players for the Olympics.
The IOC will vote next September to add one sport. Karate, roller sports, squash, sport climbing, wakeboard and wushu are also competing.
Baseball and softball, voted off the Olympic programme in 2005, were last played at the 2008 Beijing Olympics.
