Burrows has been added to the Pirates' taxi squad prior to Friday's game against the Yankees, Noah Hiles of the Pittsburgh Post-Gazette reports.
While he is not on the active roster yet, it seems likely that could happen sometime this weekend. Burrows, 24, holds a 4.06 ERA and 45:15 K:BB over 37.2 innings this season at Triple-A Indianapolis and would be making his major-league debut should he get into a game.
