The Pirates recalled Kelly from Triple-A Indianapolis Friday, Alex Stumpf of MLB.com reports.
Kelly made his major-league debut earlier this season for Pittsburgh, allowing two runs over 2.1 innings in his lone appearance. The 22-year-old has logged a 4.85 ERA and 54:33 K:BB over 68.2 frames at Indianapolis in 2026. Kelly is presumably up to provide the bullpen with some length.
