Atlanta acquired Bart (foot) from the Pirates on Thursday in exchange for Hunter Stratton.
Bart has spent the last month-plus on the injured list due to a foot infection, but he began a rehab assignment last week and appears ready to make his return to the big leagues with Atlanta, where he'll serve as the backup to Drake Baldwin while Sean Murphy recovers from a broken finger that is expected to sideline him until after the All-Star break. In just 62 trips to the plate this season with the Pirates, Bart slashed .259/.290/.379 with two homers, six RBI, nine runs scored and a 2:21 BB:K.
