Korea's Ministry of Sports, Tourism and Culture had given the league permission to bring back up to 30 per cent of fans.

KBO decided to keep the level to 25 per cent, however, so a distance of at least one empty seat could be maintained between each fan. 

"KBO and the 10 clubs welcome the Government's decision to expand audiences and express their deep gratitude to the crowds for maturely handling the inconvenience and thoroughly complying with the quarantine guidelines," said KBO in a statement.

Matches for the 2020 KBO season began behind closed doors on May 5 due to the coronavirus pandemic. 

Venues were then able to allow spectators to fill 10 per cent of its capacity from July 26. 

Spectators have their temperature checked upon entry and are required to wear a face mask throughout the game. 

Chanting, singing and loud cheers are also discouraged.

Fans are now also able to watch baseball matches in Italy, the first sport in the country to allow spectators since the pandemic. 

Around 150 fans watched Fortitudo Bologna and San Marino play in the Italian Baseball League on August 8.

Temperature checks and face masks were again mandatory. 

Both countries had contrasting experiences of the pandemic, with South Korea reporting 14,770 cases of coronavirus and 305 deaths. 

Conversely, Italy has had more than 251,000 cases, resulting in 35,225 deaths.
