I'll cover the catchers in a separate post. There are three infielders and two outfielders:
Christhian Adames (S, 2B/SS/3B), 29 in July, in pro ball since 2008, 176 G ML exp
Zach Green (R, 3B), 26 in March, 2012 3rd-round pick (PHI), 16 PA in debut with 2019 Giants
Joey Rickard (R, OF), 29 in May, 2012 9th-round pick (TBR), 343 G ML exp
Jamie Westbrook (R, OF/2B), 25 in June, 2013 5th-round pick (ARI), no ML time
Switch-hitter Adames could be a useful utility player.
