The president of world baseball's governing body on Friday played down fears that the sport's top stars will refuse to play in Fukushima if the nuclear disaster-hit prefecture hosts games at the 2020 Olympics.

Olympic chiefs are currently considering a proposal to play part of the Tokyo 2020 baseball and softball competition in Fukushima Prefecture, which in 2011 suffered the world's worst nuclear accident in 25 years when the Great East Japan Earthquake triggered a meltdown at the Fukushima No. 1 nuclear power plant.

The prefecture successfully hosted games at the Under-15 Baseball World Cup in the city of Iwaki this summer, and World Baseball Softball Confederation President Riccardo Fraccari believes senior teams will not be deterred from playing there in 2020 should its bid to host games be accepted.
