Six national teams qualified to compete in baseball at the 2020 Summer Olympics in Tokyo (postponed to 2021[1] due to the COVID-19 pandemic).
[10] The top 12 teams on the WBSC men's baseball ranking list at the end of 2018 qualified for the November 2019 Premier12 competition.
[2] The United States won the eight-team Americas Qualifying Event, and was thereby awarded the one quota spot allocated to the winner of the tournament.
The event was originally scheduled to be held from 22 to 26 March 2020, in Arizona, but was postponed to 31 May through 5 June in Port St. Lucie and West Palm Beach, Florida, due to the COVID-19 pandemic.
[18] In May 2021, due to a spike in domestically transmitted COVID-19 cases in Taiwan and new restrictions imposed by the local government, the WBSC moved the final qualifier to 22 to 26 June 2021, in the city of Puebla, Mexico.
[20] Chinese Taipei also withdrew on 2 June 2021, due to concerns related to player safety from COVID-19 in Mexico, leaving four teams and no Asian representation at the tournament.
[21] On 8 June 2021, Australia withdrew from the tournament, due to logistical issues caused by COVID-19, leaving just three teams to compete.
