To create openings, the SF Giants outrighted Tyler Heineman, Joey Rickard, and Anthony Banda off of the 40-man roster. According to Kerry Crowley of the Bay Area News Group, Banda has already signed a minor league deal for 2021.
Beede (Tommy John surgery), Garcia (hip surgery), and Moronta (torn labrum) did not appear in 2020 as each one recovered from injury. They were originally placed on the 45-day injured list to allow the Giants to make additions to the 40-man roster.
However, the 45-day injured list cannot be used during the offseason, so all three needed to be brought back to the 40-man roster.
