Appeals to reinstate baseball and softball to the London 2012 Olympic Games programme have been rejected.
International Olympic Committee members voted 46-42 and 47-43 against baseball and softball respectively.
The decision means London organisers will save around £50m for two planned stadia in Regent's Park.
London 2012 organising committee chairman Lord Coe said: "We are neither disappointed nor pleased. Regent's Park will still host the road cycling."
Baseball and softball will make their last appearance as Olympic sports in Beijing in 2008.
The decision to exclude the sports from London had been made in July but met with resistance from the governing bodies concerned and some IOC members.
Despite Thursday's vote, Japan - bronze-medallists in both sports - pledged to maintain the fight to bring softball and baseball back into the Olympic fold.
"We will think about the way to break out of this tough situation," Japanese Olympic Committee president Tsunekazu Takeda said afterwards.
"I don't believe that the door is completely closed for the two sports."
The next time the two sports may have a chance to appeal for their comeback into the Olympic programme will be at the 2009 IOC Session in Copenhagen.
