What Buster Posey’s decision means for Joey Bart, Giants’ catchers

Because the Giants were split into three workout groupsand Buster Posey missed three days, the starting catcher had not had a lot of time to spend with top prospects Joey Bart and Patrick Bailey.The latter two worked out in the mornings, alternating reps as they worked toward a future in the big leagues. That day, when Bart and Bailey split time, is at least two yearsaway, but now the Giants are tasked with deciding how soon they want to jump into the deep end with another young catcher.
