The qualifying round of the 2023 World Baseball Classic was held from 16 September 2022 to 5 October 2022. Teams which participated at the 2017 World Baseball Classic automatically qualified for the 2023 tournament. The qualifying round consisted of two tournaments to be participated by six teams each. The qualifiers were planned to be hosted in Tucson, Arizona in the United States but after the delay, the qualifier hosts were changed to the cities of Regensburg, Germany at Armin-Wolf-Arena and Panamá City, Panama at Estadio Rod Carew.[2] Winners and runners-up of each of the two tournaments qualified for the 2023 World Baseball Classic.[3]
The format was double-elimination. Each pool contained six teams, two of which are given a bye to the second round. The highest ranked teams in the WBSC World Rankings (the Czech Republic and Germany in Pool A, and Panama and Nicaragua in Pool B) received the byes.
