ATLANTA — When he starred at catcher just down I-75 at Georgia Tech in 2018, Joey Bart spent off days gathering teammates for trips to Truist Park to watch the Atlanta Braves from the Chop House beyond right field.Eight years later, Bart found himself walking into the same ballpark to gather with teammates. Only this time, he entered through security gates and clubhouse doors as a member of the home team.The Braves’ newest backup catcher, acquired in a trade for right-hander Hunter Stratton, arrived Friday to find No. 16 on the back of his jersey — the same number once donned by Brian McCann, the catcher Bart grew up idolizing. It was a reminder that the organization the 29-year-old admired from afar has maintained a winning formula since he was in college.“They’re doing all the right things to win,” Bart said. “There are a lot of winners in this clubhouse and throughout this organization. It’s more than just talent.”The Braves aren’t asking Bart to become the next McCann, but they do believe he can join the group of role players who have helped the Braves to an unexpected 47-27 record and provide a boost from behind the plate. He’s posted a roughly average OPS+ while sharing duties with fellow Pittsburgh Pirates backstop Henry Davis each of the past two seasons.
