There was no NCAA College World Series tournament in 2020 because of the COVID-19 pandemic. You can find the previous (2019) regional results here and the next (2021) ones here.
The 2020 college baseball season ended early as a result of the COVID-19 pandemic.
There was no NCAA college baseball national championship contested in 2020.
Current status: Nothing to see here!
The incomplete season results during the COVID-19 Pandemic Year of 2020 have no significance, but can be found in individual college records. The only thing I will mention here is that Mike Martin Sr, winningest coach in Div I college baseball, retired as head coach at Florida State and his replacement, Mike Martin Jr, coached his first games during the 2020 season.
A national shutdown, with college classes transitioning to a virtual classroom setting, started around spring break. Our last in-person college classes in Florida were on Friday, March 13, 2020. Most baseball seasons ended around that time.
The NCAA tournament resumed after an eventful 2021 season that began before any teams could be vaccinated, resulting in disruptions to the season, but three different vaccines were freely available for college-age athletes by the time conference championships were being determined.
