Bayi, who is an Olympian, said he has noted with great concern that domestic athletes are not preparing well for the games and said the nation should not be surprised seeing athletes return home empty handed.
The 2018 Commonwealth Games have been slated to take place in Gold Coast, Queensland, Australia from April 4 to 15.
Bayi insisted that Tanzania has competent athletes that can win medals in the event but they are not well prepared.
He singled out athletes, Emmanuel Giniki and Alponse Simbu, as the country's medal hopefuls in the games.
“ I can assure you that Tanzania has top and potential athletes who can win medals in the coming Commonwealth Games but they are not well prepared," Bayi said.
"The good thing which is also an advantage to Tanzania is that many top athletics nations like Kenya do not send elite runners in the Commonwealth Games.“
Bayi's remarks comes after TOC and national sports associations which will field athletes in the Commonwealth Games said they are keeping their fingers crossed that the government will send athletes to foreign nations for preparations for the games under sports diplomacy.
Up to date, the government through the Ministry of Foreign Affairs and International Cooperation, has managed to send table tennis athletes to China to prepare for the next year's games.
Apart from the table tennis players, other expected beneficiaries of the sports diplomacy are athletes and boxers.
“We are waiting for the government to send boxers to Cuba and athletes to Ethiopia for camps to prepare for the next year's Commonwealth Games, for sure without good preparations Tanzania's athletes will likely come back empty handed,“ he said.
