The Pirates recalled Burrows from Triple-A Indianapolis on Saturday.
Burrows has spent nearly the entire season with Indianapolis, posting a 4.06 ERA and 1.42 WHIP across 37.2 innings. Although he was used primarily as a starter, he'll most likely be used in a multi-inning role out of the bullpen with Pittsburgh. If he's able to get into one of the team's final two regular-season games, the 24-year-old righty will be making his MLB debut.
