The Giants promoted Antoan Richardson, the team's Field Coordinator, to first base coach for the major-league squad. Jose Alguacil, it seems, is let go. I always thought they were grooming Alguacil for bigger things. From a January article about Richardson:
Antoan Richardson -- Field Coordinator
Richardson starts his first season with the Giants as the Field Coordinator. The former outfielder spent the 2018 season as an Outfield Coordinator for the Toronto Blue Jays. Richardson appeared in the Majors with the Atlanta Braves in 2011 and with the New York Yankees in 2014.
