Impact Mella was DFA'd by the Diamondbacks in mid-June and the right-hander was later released on July 28. The reliever has pitched in the majors in five different seasons, with his best showing coming a year ago when he posted a 1.80 ERA across 10 innings with Arizona. He'll report to Indianapolis for the time being but could become an option to join the Pittsburgh bullpen later in 2021.
