Baseball, golf, karate, roller sports, rugby, squash and softball officials will meet the 16-member IOC's Olympic Programme Commission, which includes Britain's Sir Craig Reedie, that will prepare an influential report the organisation's ruling Executive Board.

 

The IOC plan to include28 sports at the 2016 Olympics, allowing two sports to be added.

 

The programme for London 2012 includes only 26 sports after baseball and softball were controversially voted off at the IOC's Session in Singapore in July 2005.

 

Each sport has a one-hour slot, with baseball making the first pitch in the closed-door presentations in Lausanne,.

 

To win reinstatement, baseball must show the IOC it can deliver major league players to the Olympics, which is held during the second half of the regular season.

 

Detroit Tigers centre-fielder Curtis Granderson will speak as part of the International Baseball Federation (IBAF) maximum six-person delegation.

 

Harvey Schiller, the president of the IBAF, said: "We want to do our best to tell the story of baseball.

 

"We wanted to bring a player that is a star now and also a star of the future.

 

"Curtis is young enough to be able to participate eight years from now."

 

Softball made its debut at the 1996 Atlanta Games and the Americans swept three consecutive Olympic gold medals before losing to Japan in the final in Beijing.

 

The International Softball Federation (ISF) has distanced itself from baseball in an attempt to win back its place in the Olympics.

 

Baseball and softball lost inclusion by a single vote in Singapore three years ago and the feeling was that softball was too closely linked to baseball, a sport bedevilled by drug abuse.

 

ISF president Don Porter will be joined by Olympic players Saskia Kosterink of the Netherlands and Rubilena Rojas of Venezuela.

 

The case for golf, last played at the Olympics in 1904, will be presented by the International Golf Federation.

 

It is led by Professional Golfers Association executive Ty Votaw and Peter Dawson of the Royal & Ancient Golf Club of St. Andrews, where Sir Craig is a member.

 

The World Karate Federation, with 180 national federations, hopes the global appeal will be attractive to the IOC. It proposes awarding 10 gold medals in five classes for men's and women's competitions.

 

The International Federation for Roller Sports proposes road races on city streets, but no rink hockey or skateboarding.

 

Rugby fell from the Olympic programme in 1924 and wants to return with the seven-side, shorter version of the game for men and women, rather than the more established 15-side competition.

 

The World Squash Federation will emphasize its television-friendly, glass-enclosed courts. Its delegation includes IOC member Prince Tunku Imran of Malaysia and former world champions Jahangir Khan of Pakistan and Sarah Fitzgerald of Australia.

 

Franco Carraro of Italy is the chair of the program commission.

 

He was one of eight IOC members who will question the delegations before presenting a report to the Executive Board.

 

They meet in June to make recommendations to the full IOC membership.

 

A simple majority is needed for a sport to be voted onto the programme.

 

The IOC also will select the 2016 host city during the Copenhagen session.

 

Chicago, Madrid, Tokyo and Rio de Janeiro are the candidates.
