The Pirates promoted Chandler from Double-A Altoona to Triple-A Indianapolis on Friday, Alex Stumpf of MLB.com reports.
In 18 appearances at Double-A this season (15 starts), Chandler has posted a 3.93 ERA and 1.05 WHIP alongside an 87:26 K:BB through 73.1 innings. Regarded as the Pirates' top pitching prospect, the 21-year-old righty will most likely spend the remainder of the 2024 campaign in Triple-A and look to crack the big-league rotation at some point in '25.
