If the Oakland A’s were to bring back just one of their affordable free agents, then second baseman Tommy La Stella would be the best choice. However, there are more players available on the open market than just the ones who were wearing green and gold when the 2020 season ended.
In fact, there is another free agent out there who plays the same position as La Stella, but might be an even better fit. Like La Stella, he bats left-handed, makes a lot of contact, keeps the strikeouts low, and gets on base, but on top of that he’s the best defensive 2B in the majors.
